Latest version is breaking icons for other plugins

Hi, thanks for the great plugin! I’ve been using it for over a year, and it works great.

I’m having an issue with the latest version though. When it is active, icons from the WP-ERP plugin stop working.

Here is an example if the icons in their email campaign section. It’ an issue because without the icons, I can not edit the email blast.

Old dropbox folder share version 1.8.5 activated (see working icons)

New, 1.9 version activated (see missing/blocked icons):

Any ideas?

Thanks!
