I had a Joomla site that was 1.0.13, which I upgraded to 1.0.15, then used the migration script to import the data into a new Joomla 1.5.20 on a new server.
The migration seemed to work fine in the new 1.5.20 site. However, when I try to upload anything (templates, editors, extensions) in the new site using the Extension Manager, nothing happens. I have checked my permission, and they seem the same as any other of the Joomla websites I have on this same server.
The php version is 5.1.6.
Does anyone have any experience or thoughts on this?
