Sorry for beating a dead horse here, but I found a lot of info on this topic, (too much) and the suggestions that I found don't really seem to provide a clear solution. It's try this, or maybe that, works for some but not for others. Maybe I haven't found the correct answer here in the forum (yet) but I have been searching and trying DIY for 2 days and just can't make it work. Where can I find the latest and greatest solution to this issue? Please help.
I am getting the same error on 3 different blogs but for different plugins: "Incompatible Archive. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature"
Plenty of disk space, all are 3.2.1, tried FTP and that isn't even working anymore, all three are hosted on aplus.net and their tech support says it's a WP issue that they can't help me with.
