Hi,
I am getting the following error messages when testing my website:
-Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0.
-500 Internal Server Error
-503 service unavailable error
I have just moved over my website from one domain to another and downloaded the following plugins:
<div class=””>https://wordpress.org/plugins/wp-mapbox-gl-js/</div>
<div class=””>https://wordpress.org/plugins/mapbox/</div>
<div>https://wordpress.org/plugins/osm/</div>
What can I do to fix this? Is this a theme issue, plugin issue, or an issue with any of my website’s contents?
I have already maxed out the WP memory so I need to know how to fix this ASAP.
It also has these issues:
- loads very slowly on each page
- sometimes does not load rev slider
- does not load one of the pages [/impact] at all. it is completely white except for the header
