One of the sites i'm working says that the modules folder is not writable. I'm sure you know the error well, but here it is anyway...
I have read through the forum, and done the followingThe modules folder is not writable, if you would like to install modules by uploading an XML file you need to make the modules folder have full read/write/execute permissions (chmod 777). Safe mode may also be in effect
- checked permissions on the modules folder is set to 777
checked permissions on uploads folder is set to 777
checked that php isn't running in safe mode
reinstalled cmsms
phpinfo confirms that other sites i maintain are on the exact same server - and they work perfectly thanks to cmsms

Anyone got any other suggestions?
Thanks!
