would be faster if you post the error logs here if they are large upload them to a zip file

the problem its not making error logs.... :(

Actually, please do NOT post the full error_log. Upload a gif to your site and then go look at the error_log for your IP at that time. Only post *that* error.

Please add the following line to your config.php file under the <?php line:

Then upload a product and see if you still have the same problem.

That what I meant :D

I had a similar problem i had to rebuild my server it was something with my DNS setting.
Try to upload a mod using IE. IE would tell me the problem there where no errors in my error log too but ie told me that my DNS was misconfig

Upload a gif to ftp ????

I did this but cpanel error don't show it ...nothing

Sorry, I meant to upload a *product*.

Please try to set MySQL Packet Size to 128.00 MB, Than try to Importing Product. I think this way you can do fixing this issue !

I have other new instalation in same server. This new forum works correctly but has the default configuration of vbulletin :/
