Hello, good morning ...
I have a problem with my site I am using joomla 3.1 all works perfectly. the problem comes when installing Roksprocket once installed and want to enter the module manager shows me 500 error as if I enter pantillas manager. is that roksprocket Rokcommon is installed with. when I can turn off manually enter Rokcommon and managers already mentioned. I tried uninstalling and roksprocket rokcommon and reinstall and keeps sending me the same error. I have PHP, Apache, Mysql with the latest version I hope I can help.
Is everything up to date on your site (Gantry, Joomla, Template, RT Extensions)? If everything is up to date and the issue is still not fixed, please send me a PM with a link to your admin and login details so I can take a direct look.
