For the last few days, I am having a problem with the Word Press. It appears that a post above a particular size is not getting published or updated.
If I post a screenshot image this post also cannot be uploaded.
The error message says
Quote
Not Acceptable
An appropriate representation of the requested resource /wp/wp-admin/post.php could not be found on this server. Additionally, a 406 Not Acceptable error was encountered while trying to use an ErrorDocument to handle the request.
Unquote
Can anybody suggest how this can be rectified?
Help will be highly appreciated.

P.S: The problem was identified as a Mod Security on the server. Has been set right now.
Looks like a modsecurity issue. You can try this after backing up the original config files:

Please review the implications of the changes mentioned, before modification.
Thank you. I think the issue has now been resolved. I checked the article and it was useful.
