Do you have a link to the website?
What versions of BuddyPress and WordPress are installed?
What theme are you using? Have you tried the default theme?
Hey Tammie. Thanks very much for that video. I followed your tutorial and it worked perfectly. The only issue I had was the preview in the admin panel was using the old sizes but I managed to solve that with some CSS tweaks. Just need to figure out my adminbar problem now 
Thanks!
I think that’s in `/members/single/member-header.php` Just be sure to use a child theme when you make the change: https://codex.buddypress.org/theme-development/building-a-buddypress-child-theme/
I too am getting the error but only in a few of the BuddyPress themes. I get it in the BP Nicey, the BP default, & the Fishbook theme. I would love to have it fixed especially with the Nicey theme.
Just remember that if you edit core bp files/templates, you will lose your changes (and will have to redo them) whenever you update Buddypress. If you really need a header image of a different size, it is preferable to disable custom header support in wp-config, upload your image, and hardcode the URL in a child-theme style.css.
I should also mention here that sub blogs are subdomain configuration and I’m using default theme with bp colors orange child theme. One thing I thought of is that I took out the “members” base using config file method mentioned in buddypress codex. Hosted on hostgator shared with dedicated ip. MU site is main domain on account. Hope this gives someone more relevant info to help.
Yeah, thanks a lot for your help Tammie 
Assuming you mean the custom header that you find under appearance > header then here is a blog post with a tutorial.

Excuse just linking but it pretty much sums up easier than me saying to you what to do and hopefully will help as a reference.
If it’s not custom header just let me know.
What happens with your blog Themes? Do they do not work, or is the display messed up? BuddyPress and MultiSite should work fine and your WordPress themes on sub blogs should display fine with the addition of the Admin bar at the top.
If you want a theme that matches your main blog you can adept the default theme to become a regular WordPress Theme or look at themes that do this for you 
I can integrate your WP theme to BP. If you need help just let me know.
I’ve faced this question so many times I decided to write a wiki page about it—it’s not as detailed as I would like, but it should get you started with customizing the themes.

Hope that helps.
Thanks Michael,
the stylesheet works when I paste the URI’s above. I would like to get a better understanding of Uniform Resource Identifiers and requirements in css. Do you have any good references?
@xevo
The colors for the basic theme are intentionally bland or harsh to encourage customization, and the shadow effects can easily be removed.
And thanks! I will keep at it.
We need more BuddyPress themes, but can’t really say I like the colors and all that shadow..
Other then that, it’ll probably be a good template to work out off. Keep at it.
2nd progress report…
Just got back from a week with my Dad. Good news is: BuddyLite for BP1.2.5 is almost ready for release
The CSS has been cleaned up and simplified to make it as easy as can be to create custom styles for this theme (just make a few mods to each of 6 on-screen elements and, BAM!, you’ve got your own unique style).
The 20-page illustrated users manual is finished; a comprehensive, easy-to-follow, how-to-customize-this guide for newbies.
I decided to include the widgetized footer panel in the freebie also, ‘cuz it just fits so well with the homepage.
I’ll be updating the theme for BP1.2.6 this coming weekend and, if all goes well, the 2 versions can be released together.
Then… work begins on the Premium version.
I’ve posted a few more screenshots to my little blog of what’s to come (to keep everyone’s mouths watering, I hope)

Is there a reason for that approach? is not the aim to replicate the original themes layout for better or worse, not that what you have suggested doesn’t work but does leave a mix of markup layout between files?
Ok on second look it seems the sidebar on your theme is in a different placement inside #container. So another approach may be to move that code.
yes I used the template pack and am turn my theme into a buddypress theme. I am kinda new to this so what do I do? I don’t really understand.
Can you provide a little more detail, like what theme? Is it a custom one?
Simple answer: you can wrap the sidebar call on pages in conditional queries that test to see what page is being displayed, check out the BP codex you’ll find a list of conditional tags you can use or even simpler answer remove the locate_template function in the file for the page you don’t want the sidebar appearing on.
@nahummadrid thanks again for the post, I got everything working quite well!
@r-a-y Thanks for the input. I have solved the title page issue as per your link provided thanks!
Still battling with my main site being seen as a secondary site on the bp-default install (running on a sub-directory) I have only activated bp-default on the subdirectory as suggested. Both sites run well, but under the blogs tab in bp-default theme all my other sites are showing on the community site as well that shouldnt be there. Is this just a basic setting I am getting wrong here or am I trying to do something thats not possible!
Lets take a wild stab in the dark… actually lets not, instead why not try and provide some detailed info about your setup, versions, themes, plugins etc along with as much information as you think may be helpful to troubleshoot your issue – that sort of detail is basic and mandatory on any tech support/help forum.
First thing you could do before posting back is disable BP and any plugins and see if you can register users on the plain WP install – this will just establish it’s a BP issue or not, if a BP issue then enable BP but disable all plugins and see if that allows regitration, if so then enable plugins one by one checking each time until culprit is found.
I presume you have used the template pack to prepare BP pages under your chosen theme, Template pack will require that certain elements are added from the original theme markup to the new bp pages, looking at the layout shows that the original theme uses a nested element under #container called #left-div which is floated right and given a fixed width allowing room for the left sidebar. it looks as though this is missing from your bp pages and will need to be added in manually.
It may help you to open and reference one of the original theme files like ‘index’ , ‘page’, or ‘single’ and compare it’s main markup structure to the bp files and ensure that they match.
Make sure your style.css starts with…
