I am currently running wordpress 4.6 I am unable to edit the widgets in the various sidebars on the site. Extensive testing has narrowed the issue to the Amember wordpress plugin. While the amember wordpress plugin is active, the sidebars are not visible and widget sections cannot expend/drop down. As soon as the amember plugin is disabled, everything works normally. I have tested this with all plugins enabled (except amember), with all plugins disabled, and with a different theme. The behavior remains the same. Every time it's the amember plugin causing the issue. Has anyone else seen or experienced this issue? Any ideas on a fix? Thanks! KM
The most common issue for this is incorrect plugin files upload. Try to reupload amember4 plugin files again and make sure that all folders have 755 permissions and all files have 644 permissions.
