Error Category not found, When create/ Edit Article

Postby mibrahim » Wed Oct 18, 2017 11:56 am

My problem is i keep getting "Error Category not found".

This happen When create/ Edit Article. But not on all cases like normal text will not cause any problem it will be saved. But when for exampling adding image it will not save or edit. And will get the error mentioned.

-Not new Installation and was working fine for enough time.
-Joomla! Version Joomla! 3.7.3 Stable [ Amani ]
-This will happen when "Search Engine Friendly URLs" On or Off
-upload_max_filesize = 24M
-Text Filter is normal like for example Image

No ... make a backup of your site and update.

Even still, you need to update.

Also try: Extensions > Manage > Database: Fix database.

Also run: viewtopic.php?f=621&t=582860

Fixed Now:
After Security update on the hosting server,
The modsec security thought the WYSIWYG editors is performing a SQL Injection (a false positive).

Sorted by adding rule exception in ModSecurity™ Tools section of WHM

<LocationMatch "/administrator/index.php">
SecRuleRemoveById 941100
SecRuleRemoveById 949110
SecRuleRemoveById 980130
SecRuleRemoveById 941160
</LocationMatch>

Or was it picking up on the vulnerability that Joomla 3.7.4 fixed ?
What's in 3.7.4?

Joomla! 3.7.4 is released to address security issues as well as several bugs.
Security Issues Fixed

Core - Installer: Lack of Ownership Verification (affecting Joomla! 1.0.0 through Joomla! 3.7.3) More information »
Core - XSS Vulnerability (affecting Joomla! 1.5.0 through Joomla! 3.7.3) More information »
Visit the Security Centre for more information.
https://www.joomla.org/announcements/re ... lease.html

Not to mention the security fixes in 3.8.0
Security Issues Fixed

Core - Information Disclosure in LDAP Authentication Plugin (affecting Joomla 1.5.0 - 3.7.5) More information »
Core - Information Disclosure in com_content Archived Articles Model (affecting Joomla 3.7.0 - 3.7.5) More information »


I won't (for obvious reasons) point to the pages that explain how to hack the non updated sites ... but but any 'script kiddie' can find how to hack your site. Once it has been hacked it will go on a list and several hackers will upload script that will allow them to control your server.

So you have updated Joomla ?

If you have updated Joomla do you still need those exception or will Joomla function correctly without those exceptions ?
