403 Permission Denied - vash - 2010-09-19

Just started getting this error message when trying to access my admin panel. Haven't actually done anything so am a little baffled as to why this might be!

Any suggestions gratefully received!

On gamersforum.org. Actually renamed admin to something else to make it more secure, when I first installed Mybb. Was fine yesterday so this is a new problem. Haven't made any chanegs.

What version of MyBB are you running??? You shouldn't be getting these errors unless you have 1.4 code running.


RE: 403 Permission Denied - vash - 2010-09-19

I am definitely running 1.6. I haven't installed any plugins that are not meant to be compatible with 1.6. Could it be that one of them has incorrect Compatibility settings?


RE: 403 Permission Denied - Sajuuk - 2010-09-19

1.4 plugins are not going to work on 1.6, there were plenty of announcements that stated this. Open up the plugin file, and change the compatibility from 14* to 16*.

It could also be that the plugins use old style links for the AdminCP or that the admin folder doesn't have 755 permissions.


RE: 403 Permission Denied - vash - 2010-09-19

Yes, I said I didn't install any plugins that were not designed to be compatible with 1.6 and I have just checked and none of them are for 1.4.


RE: 403 Permission Denied - Sajuuk - 2010-09-19

Have you checked that your admin folder has 755 permissions and the files inside have 644??


RE: 403 Permission Denied - vash - 2010-09-19

Ok. None of the plugins are for 1.4, they are all for 1.6. I have only installed plugins I think that come from reputable plugin designers. How would I find out whether any of them use old style links to admin?

The admin folder definitely has 755 permisssions.


RE: 403 Permission Denied - Sajuuk - 2010-09-19

I can rule out old style links as a cause.
Do the files inside the admin folder have 644??

If that's correct, then likely you have a misconfigured mod_security on your server.


RE: 403 Permission Denied - vash - 2010-09-19

Ok, I just looked at all the folders inside the admin folder. All the files are 644 and all the folders are 755.

A misconfigured mod_security? How would I check that? It was working fine yesterday! :'(
Ok, I just renamed .htaccess and can now login, so somehow I corrupted my .htaccess. :'(

Will recreate my .htaccess. Many thanks for your help!


RE: 403 Permission Denied - Sajuuk - 2010-09-19

You'll have to ask your host to see if mod_security was tampered with. In all honesty, I would suggest turning it off.

If that didn't work, file it as a bug as I'm all out of options.
