Well, you know, that would have been my next related question. I am having a heck of a time with the simplepie.php file! I use FileZilla (and I love it), but the aforementioned file seems to be trying to upload over and over, and over and over, and over again! I watched yesterday during the transfer, and the location of the file on the remote server was showing the correct file size...then soon after that, incorrect size, like it was shrinking!?? Then the numbers would increase again to its correct file size...then again, shrinking numbers...VERY weird!
I also tried to re-upload (overwriting) the entire "includes" folder that this file resides in...having read somewhere that doing this solved someone's similar problem. Didn't help me at all, in fact it caused me to have Fatal Errors. Sooo, I deleted all of the WP directory, then re-installed...and got logged in, but now I have this issue with that one particular file.
Otherwise, the blog seems to be OK (except for memory issues discussed elsewhere at the forum). But please, if anyone can advise what to do to resolve my troubles with the simplepie.php file, I would be eternally grateful!!! It isn't even a huge file. But I can't seem to upload it...
