I solved my own problem for a change!
I deleted the plugin files from my host server. I use Bluehost and found them by following:
– File Manager Icon under Files
> choosing Web Root (public_html/www)
> clicking GO
> wp-content > plugins > then deleted affected plugins
I then went back to my WP admin screen, searched, installed, and activated the plugins again and it worked.
I think what happened was the first time I downloaded them to my computer then uploaded them to wordpress. This should work but my computer automatically unzips downloaded files. I had to re-zip them before uploading them to wordpress and probably when I re-zipped them it changed something in the header.
Thanks t31os_
I’m actually on Mac but I used Finder > Get Info to change the file to read & write for Me, staff, & everyone. It worked. I figured read & write for the administrator would be enough. Guess not. Thanks for the quick responses. As usual, it was easier than I thought at first.
