I tried to send you a screen shot. Here is a URL I went to today that showed the error:
https://www.blueridgepride.org/wp-admin/update-core.php?action=do-plugin-upgrade
Warning: Illegal string offset ‘http_code’ in /home/bluerif1/public_html/wp-content/plugins/envato-update-plugins-master/lib/class-envato-api.php on line 338
Warning: Illegal string offset ‘api_error’ in /home/bluerif1/public_html/wp-content/plugins/envato-update-plugins-master/lib/class-envato-api.php on line 338
Warning: Invalid argument supplied for foreach() in /home/bluerif1/public_html/wp-content/themes/enfold/framework/php/auto-updates/class-pixelentity-theme-update.php on line 91
If I go back to that URL, I get the error again. It seems to show up on some admin pages and not others.
I think I figured out the cause. When I deactivated an advanced editor from JoomUnited, the problem seems to have gone away.
[Wow! Testing conflicts is complicated! You guys must work hard. Hats off to yhou!]
