ok mind you im a novice i asked the server people if the server untars stuff he said it does not, im not even sure if that is need or the script does it
Same error i reported here
Maybe disk quota exceeded in folder '/tmp'.
I got that error while trying to install some wbb plugins, never got an answer not from my hosting or from wbb staff i mean an answer that may fix this isssue.
But i will tell you what i did to can install the plugins that gave me the error, i installed xampp on my pc, installed the forum there and the plugins with no problem, then i added everything into an archive and uploaded on my hosting, untared there and also updated my database with the one from my pc. This worked for me so i gave up expecting an sollution for this issue that might be hosting issue or wbb issue but i think is hosting problem
