It's really a server question. Uploading files. I've always uploaded mod files to the server without using ftp. Just upload the zip file thru the file manager & extract. It's always worked.
I broke the last mod I installed. It had php, js & xml files to upload to the server and a product xml file to upload to the admin cpanel. I thought there was a problem with it, (turns out it worked perfectly, it was an IE/cache issue!) so I uninstalled/reinstalled the product xml file w/overwrite thru the admincp. But didn't do anything to the server files.
Apparently it's a big no-no to uninstall, (according to vBulletin.org mod thread), because it deleted a table that the mod created.
Can I get that table back by uploading the files to the server again? Can I just delete the files in the server, and upload them again? (I've already tried to upload/overwrite each file separately and that hasn't seemed to change anything.) Or do I need to uninstall them and upload again? And if so, with either route, will it hurt anything? I've never uninstalled anything at the server level, so it's scary to me!
