I have had problems uploading images to my media library. Whenever I attempt to, I get a HTTP error. I read several forums about it, and the general consensus was ‘deactivate all plug-ins, reactivate one at a time and see which causes the problem’. I’m afraid it was my SiteOrigin Widgets Bundle that caused the errors.
Are you able to advise? Or update the plug-in to avoid this again as it’s a great plug-in and I love the widgets.
