Many plugins not working

I had this posted in installation so moving here hoping to get more responses. I’m going to update it…

Almost any plugin that I try to activate either doesn’t work at all or can’t be configured or some other issue. Not sure if it’s related but previewing a theme usually shows up blank but then works when activated. I checked file and folder CHMOD permissions for the plugins and they looked alright at 644 and 755 respectively.

It’s a clean 2.7 install (no previous version). The only thing I copied over from a previous version and another domain I manage is a theme I edited (image changes mainly) and the unzipped themes and plugins. I then installed them through the Dashboard. Because of the problems encountered I also tried deleting the plugin(s) or themes and reinstalled with the same results/problems.

I really need the Evermore plugin to work after a variable number of paragraphs. I tried to contact the author with no luck yet. So if I can’t get this evermore plugin going does anyone know how I can manually do the same thing?

Thanks in advance for any help.
