I'm writing in behalf of our client that is using WP Media Folder plugin on his website on our server.
When using the plugin, we noticed query
SELECT option_id,option_value FROM wptm_options WHERE
option_value REGEXP 's:[0-9]+:"
was extremely slow, even though wptm_options is not large and that is only a test website, not even a production one.
I was wondering, are there any special system requirements for this plugin? What are the minimum requirements? Are here any known incompatibilities with MariaDB mysql servers?
