Let’s see if this is ab it more helpful for you.
I’ve activated Your plugin. Apache starts giving me the following error.
[Sat Oct 10 14:33:53.866214 2015] [core:alert] [pid 2924] [client 148.101.11.104:55132] /var/www/wp-content/plugins/wp-admin-bar-removal/.htaccess: DirectoryIndex not allowed here, referer: https://example.com/wp-admin/plugins.php?deleted=true&plugin_status=all&paged=1&s=
Decided checking out the following file, due to the error message above:
/var/www/wp-content/plugins/wp-admin-bar-removal/.htaccess
I commented the following line, since it seems to be the source of the problem.
DirectoryIndex index.php /index.php
The error changed to this:
[Sat Oct 10 14:32:43.120331 2015] [core:alert] [pid 2870] [client 148.101.11.104:22285] /var/www/wp-content/plugins/wp-admin-bar-removal/.htaccess: Invalid command ‘Header’, perhaps misspelled or defined by a module not included in the server configuration, referer: https://example.com/wp-admin/plugin-install.php
Any ideas on what can be causing this?
