# Developer down?

 * We are using the latest version with pro-plugin – and we have a lot of performance
   problems because the developer-website is down?! Our admin menu is very very 
   slow… I think the plugin wants to check the pro-version and can´t connect to 
   them. So all is slowing down. Disable the pro-plugin helps.
 * Whats wrong at the moment? End of support or “only” technical issues/problems?

 * If you go into the main php file for the plugin and comment out the line 143.
 * It will disable the updater, and should make it work normally again.
 * had to do this for mine, the code to retrieve the update kept crashing my backend
   as well.

 * No. This one: …/xyz/wp-content/plugins/file-manager-permission-system/file-manager-
   permission-system.php
 * The changes are only needed in pro-version.

 * The usual reason for WordPress admin panel slowness is broken DNS.
 * Most Distros now use systemd, which in turn uses systemd-resolved, which is badly
   broken. Meaning this code fails to correctly cache DNS lookups.
 * The result… Each admin page visit requires looking up all remote links, like 
   external site API calls. Since DNS caching is broken + calls to down sites have
   a timeout of many seconds or minutes… admin pages slow to a crawl.
 * The fix I use for all my hosting clients is strip systemd-resolved out of all
   LXD containers (use to host client sites + APIs) + replace with dnsmasq.
 * Using dnsmasq tends to fix many slow admin page problems.
 * Unfortunately most hosting companies are clueless/useless, so if you admin your
   own servers, strip out systemd-resolved. If not, it’s unlikely you’ll find a 
   hosting company able or willing to do this.
 * You can tell if this is your problem by installing the Query Monitor plugin +
   then run with SAVEQUERIES enabled in wp-config.php + look for changes to red (
   slow) in the Query Monitor status bar.
 * When the bar turns red + clicking on it shows many HTTP requests in red, then
   it’s very likely you’re getting hit by the systemd-resolved broken code problem.
