I used with this module rmcommon.
When I want to uninstall this module , system site do no not go to administration of page module.
When I click on administration modules from module system page redirect to …/modules/rmcommon/modules.php and this page give this message “this moudule do not exit.”

I can not reinstall this module rmcommon and any module because I do not have access to administration modules page.

System Xoops : 2.4.5
Rmcommon : 2.075a2

Hello, I think to install rmcommon you have to overright a core file you should also have installed the redmexico admin gui as I think its required.

Make sure you have replaced any overwritten core file with the original file and uninstall redmexico gui as well.

I remember having trouble when trying to uninstall rmcommon from a test install, try the above and also remove all rmcommon files from the server and try that
