This is a theme problem. Try using the default BuddyPress theme.
Yeah great idea default theme, why bothering with your site looking unique? Why i even bought expensive theme and widgets?
What a ridiculous response…
@flyj4ck – Don’t be a jerk.
Your theme has a CSS problem.
I would add that if you want better support, you might consider providing more details about what you tried and what you didn’t try to fix the problem.
Rather than tell us what is broken, tell us what you tried to resolve the situation from a CSS/code perspective.
Okay, this is themeforest theme – Gonzo
I tried creating new page for example activity and setting it up as full widght, but it didnt help.
Thats all 
You need to install/activate the BP Template Pack plugin to make any WP theme compatible with BuddyPress. Then you have to go through Appearance > BP compatibility process.
@flyj4ck Re Gonzo theme. Recently helped someone with the compatibility process and I assume it’s the same theme https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/buddypress-issue/ If you have any issues after following the instructions, post in that thread.
Please be courteous.
final step: D. Final note: Copy the style modifications for some BP elements https://codex.buddypress.org/theme-development/theme-dev-bp-template-pack-walkthrough-twenty-ten-bp-1-5/3/ and paste those at the bottom of your theme’s stylesheet, then adjust to taste.

Guys i really need help. Only issue i have is with this forums
http://liju.pl/fora/
Its my forum index
I beg you for help!
== BUT i want either sidebar on the right side or none at all. and i still get sidebar under all content ==
You have to follow the instructions in the link I gave above.
– COPY the whole header.php file and Save As header-buddypress.php then ADD the two lines I posted. Save file and upload to server.
– COPY the whole sidebar.php file and Save As sidebar-buddypress.php then ADD the two lines I posted. Save file and upload to server.
I don’t see those markups added in your current BP component pages.
i did it man i did it
i uploaded and nothing
i just want to fix the forum index problem thats all…
== i just want to fix the forum index problem thats all… ==
The forum index along with the other BP components are affected by the two BP compatibility files we created for this theme. Did you upload the two files to server wp-content/themes/gonzo, same level where you’d still find the sidebar.php and header.php files?
Yes i did, but i did just uploaded them i didnt link them anywhere if thats u askin
They are at /gonzo next to normal sidebar and header
== They are at /gonzo next to normal sidebar and header ==
If so, then something’s wrong with the BP folders/templates transferred to your Gonzo theme folder and that’s why these BP templates are not picking up header-buddypress.php and sidebar-buddypress.php you uploaded to your theme folder in server.
One solution is to get a fresh set of templates. Delete the 6 BP folders transferred to your gonzo theme folder in server – /activity, /blogs, /forums, /members, /groups, /register – then re-run Appearance > BP Compatibility again to make sure that you have clean template files.
I did it like 10 times, same result 
Is there any code i could add to CSS template file to fix index main of forums?
== Only issue i have is with this forums ==
No, you have an issue with all BP pages. Bringing your attention to the fact that the footer div is missing from the BP pages.
== I did it like 10 times, same result ==
What did you do 10x? Did you delete the BP folders in wp-content/themes/gonzo then re-run Appearance > BP Compatibility?
yes i did rerun and its even worse cause then sidebar is under it
so i deleted sidebars and footers from all bp pages
now i only need to fit bp pages insted theme , cause they going out to the right a little.
You cannot delete the call to footer.php in the template file as you’re now missing the closing tags for the containers for some divs, article, as well as closing body and hmtl tags.
1. Let’s go back to deleting the 6 folders.
2. Then Re-run Appearance > BP Compatibility.
3. Then upload the header-buddypress.php and sidebar-buddypress.php as I have instructed in this post https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/buddypress-issue/
4. Then STOP and post here so I can see what’s wrong. Do not remove anything as it might just be a matter of adding a style or so in your themes’ style.css file
Ehh i cannot do it at the moment, because my site is running with visitors.
I will try to setup second wordpress instalation with this theme. But i am hopeless, cause you did not help the other guy with Gonzo as well…
Plus i did everything right, i deleted sidebars After i did corectly ur steps, because i needed it to work.
flyj4ck, we try to help as much as we possibly can. The other person with the Gonzo did not come back to give the site URL so I could help him/her out. We’ve template-packed more than 100 themes successfully already, for free at that.
As for your set-up, as I mentioned above, I need to see what happened after #4 because you have a premium theme which I am not about to purchase for this purpose aside from the fact that I roll out my own themes. Let me know when you’re ready.
