Unable to Post Anything on Wall

[Holly]

Last night I ran into an error when attempting to post an image (see attached).
This error continued today and no I am unable to post anything or even “like” a previous comment.

I double checked to make sure everything has been updated.

The only place comments can be made is in the forums.
The last WALL comment was posted over 19 hours ago.

What am I missing?
Why is the wall aspect frozen?

@holidayjoi sounds like you have a plugin conflict with the post action and ajax. You should try disabling plugins systematically and check which one is causing the issue.

Thank you for getting back to me.

I disabled SiteOrigin Widgets Bundle and now Updates are working again.

I have not added any new plug ins, so moving forward, how can be proactive on things like this not interrupting the usability of my membership site?

[Holly]

Update
shortly after disabling this plug in… now running into the same errors.

Where can I go to get more specific help on this?

@tjchester
All plugins aside from Memberium and i2SDK (and of course all BuddyPress/BuddyBoss related plugins) have been deactivated. The problem persists. Posts to GROUPS functioned for about an hour and then stopped, again.
Is there a known conflict?
Everything is up to date.

(I also got a 504 error when trying to post here….)

@vapvarun
We are specifically getting this error
POST /http://oursitesnamehere.com/wp-admin/admin-ajax.php HTTP/1.1″ 500 20 “http://sitename.com/groups/groupnamehere/

The Apache error log shows:
odSecurity: Warning. Match of “rx ^POST$” against “REQUEST_METHOD” required. [file “/etc/apache2/mod_security/custom/wpbrute.conf”] [line “9”] [hostname “http://oursitenameedited.com”%5D [uri “/wp-login.php”] [unique_id “Ve782Ugv9BIAACOaUR4AAAAO”]

I apprecate any insights you may have with that data…
