@colinl255 – if you switch to a default theme like 2015, 2015 – does the same thing happen?
Have you also tried the issue with all plugins disabled except BP?
Have you checked that you set “pretty permalinks”?
@djsteveb – I have tried it with the default theme. The same issue occurs. I have also disabled all other plugins. Pretty Permalinks are in use.
@colinl255 – I am not sure what your issue is, and I am not a wp / bp expert.. but first thing I would do is make a backup of your htaccess file or rename it.. then make a new – change permalinks to something else, save, then change them back to pretty.. and see if it’s an issue caused by your htaccess file..
then I would make a zip backup of all files in your directory, export a copy of your database through phpmyadmin (check the advanced box to add / drop /whatever is suggested in wp codex for backup / export / migrate instructions)
delete all files in your wp-admin/ folder and wp-includes/ folder – re-upload fresh files from the latest WP download..
try again..
then start deleting plugins and themes (instead of just deactivating)
if it gets to a point where you need to wipe out everything and do a fresh install it would not be that much work.. but hopefully you will find an issue before getting that far.
I suppose it would be wise to check your server’s error log and ask your server support peeps to take a look – there could be some hidden mod sec module out of whack or something.. and they should check to see if your php and sql are up to date.
