    I'm sorry to bump an older post, but I'm having the same issue with VBulletin 4.2.5 and I am unable to resolve it. This just began happening and I have no idea why. I'd really appreciate any insight into this that could help.
    Thank you.

      Thank you.
      If it used to work, but now doesn't, then something has changed on the server.

      First thing to look at is php version. What is the exact current version, and has it been changed recently?

        Thank you Mark. I’ve not changed anything but I will check with my hosting company on the server end. I really appreciate your reply.

        Edit: Issue resolved. It was a matter of adding whitelisting rules to ModSecure. That corrected the issue. Thanks again.

          Hi Scream And Fly,

          I'm with the same problem, could you share what rules do you added to Modsecure?

          Thanks.

            Rather than use what someone else did, you need to check your own logs and find out which rule is causing it.

                That's usually because a character being copied (like a fancy looking quote or apostrophe) isn't part of the character set being used in the database and causes an error. Can you check your database tables, are you using utf8 or latin1 coalitions?

                    I don't believe that in my case is the character enconding issue, but something to do with rich text and the advanced editor.

                    If I edit a message pasting a plain text (even with latin characters) and save it, there's no problem, but if I try to do it with rich text content (with URLs for example), then nothing happens.

                    Thanks.

                      This is to do with trying to paste content from websites or other irch media into the editor. It isn't really designed to do that, and when you do it it will do its best to translate it into something that can be displayed. The results can be unpredictable however, and can also trigger server security software.

                      If this causes issues, use the plain text editor for such things, then it will paste only the basic text.

                        Hi Mike, you're right, I just catch a trigger in Cloudflare from my IP address while trying to edit a post with rich text.

                        These are the rules that I broke on the Cloudflare firewall:

                        OWASP_CRS/PROTOCOL_VIOLATION/EVASION-REQUEST_BODY
                        OWASP_CRS/WEB_ATTACK/COMMAND_INJECTION-ARGS:MESSAGE
                        OWASP_CRS/WEB_ATTACK/XSS-2000000412_251
                        OWASP_CRS/WEB_ATTACK/XSS-ARGS:MESSAGE
                        OWASP_CRS/WEB_ATTACK/XSS-2000000408_182
                        OWASP_CRS/WEB_ATTACK/XSS-2000000412_265
                        OWASP_CRS/WEB_ATTACK/XSS-2000000412_265
                        OWASP_CRS/PROTOCOL_VIOLATION/EVASION-REQUEST_BODY

                        The edit post problem disappears if I disable the Web Application Firewall in Cloudflare, but I'm no comfortable in doing so. Is there anything I can do besides disabling these rules?

                        Thanks.

                          Your only option would be to disable the rules causing problems, if that's even possible.

                            It is, I narrowed down to 2 rules that were causing the problem:

                            - OWASP_CRS/PROTOCOL_VIOLATION/EVASION-REQUEST_BODY
                            - OWASP_CRS/WEB_ATTACK/XSS-2000000412_251

                            I just did not understand why this started happening now after I updated vBulletin to version 4.2.5. Previously these same rules existed in Cloudflare and there was no such problem.

                              No changes were made to the editor in 4.2.5. It is in any event a standard editor made by a third party (CKEditor).
