I got the theme installed, but every time I try to install the plugins the entire site breaks. I already increased my PHP options (max upload size, max import, etc.) as requested. It's still causing everything to break. I get a http 500 error.
You said Oxie Core plugin can't be installed. Hmm.. nobody had any issue with installing this plugins. Do you mind if you give me temporary admin access in to your website so I can see whats going on? Send it in private message.
