Be sure to change the name of your plugin folder back to its original name of “plugins”
Enable all your plugins at once – Once you are back in to the plugins section of the WordPress admin, and all of your plugins have been automatically disabled because of the step above, you can try this option by “bulk enabling” all of your plugins. WordPress should enable anything that doesn’t crash it and will disable any plugins that produce “fatal errors.” If any of your plugins are automatically disabled, they could be your culprit.
Enable plugins one at a time - Optionally, if you are having trouble with the “bulk enable” step above, you could try to enable each plugin one by one.
Once you identify the problematic plugin or plugins, see if they have been updated. If they have, delete the ones on your server and replace with the newer versions. Hopefully that will work. Otherwise, just leave the bad plugins de-activated until they are updated.
