In WordPress Admin, all features work, exept Appearance>Theme Options and Settings. Both of those menu items display a 500 external server error page. Can’t change anything in Weaver xtreme. The Appearnce>+ Xtreme Plus item displays fine.
The host has increased the memory_limit to 256MB for me as evidenced by the phpinfo.php page. This did not solve my inability to access the Weaver Xtreme > Theme Options or Settings page in the WordPress admin environment.
Thanks for the comment. Wouldn’t you know, going to the Updates page presents a 500 Internal server error page, as does going to the Dashboard home page and clicking Reinstall Now for WordPress 4.3.
