I upgraded from 2.5.1 to 2.9.2 in hopes to fix the sudden, inexplicable inability to upload an image. This did not resolve the problem. I have searched the forum endlessly, done the standard response from moderators (deactivate plugins, reactivate one at at time, increase memory, etc). There doesn't seem to be a solution and others seem to be frustrated with this as well.
Here's my original post:
I can edit my photos once uploaded (they are in the uploads folder on the FTP) but the thumbnail does not exist and only a photo icon is visible when inserted into the post.
If anyone has been able to fix this, please post your step by step solution, as I'm still figuring out the code and where this function is located within the wp files.
Many thanks in advance!
