Addons stopped working

Hi,

I have Envira Gallery, Standalone addon, Album addon, and few other addons. A few weeks ago, it stopped working. I removed Envira Gallery folders in the server, re-uploaded these plugins, and reactivate one by one. I can have Envira Gallery with Standalone activated or Envira Gallery with Album activated, but Standalone and Album addons cannot be both activated. If I activate both, then my website and WP admin page would show this:

The website page isn’t working
website is currently unable to handle this request.

Please help me with this issue, thanks!
