Symptoms

When loading Applications tab of a domain in Plesk or while trying to install any application, the following message is displayed:

Search results could not be loaded at the moment. Retry

In 'C:\\Program Files (x86)\\Parallels\\Plesk\\admin\\logs\\php_error.log' :

[2014-12-07 07:09:03] ERR [panel] APS Catalog error exception: exception 'Exception' with message 'Failed to parse metadata' in E:\\Program Files (x86)\\Parallels\\Plesk\\admin\\plib\\aps_php.php:119
Stack trace:
#0 E:\\Program Files (x86)\\Parallels\\Plesk\\admin\\plib\\aps_php.php(119): getpackageinfo('E:\\\\Program File...')

Hitting at least one application at Tools&Settings > Application Vault > Installed Apps > application_name gives the following output:

Exception: Failed to parse metadata
file: E:\\Program Files (x86)\\Parallels\\Plesk\\admin\\plib\\aps_php.php
line: 119
code: 0

Cause

APP-META.XML files have incorrect permissions, specifically missing Full control permission for ' psaadm ' user. Missing folders.

Resolution

  1. Clear cache in Tools & Settings > Application Vault > Clear cache .

  2. Locate 'APP-META.XML' files in 'C:\\Program Files (x86)\\Parallels\\Plesk\\var\\apspackages\\' folder, e.g.

    C:\\Program Files (x86)\\Parallels\\Plesk\\var\\apspackages\\feafef33-ba0d-41d8-bcbc-d22db27049a7\\APP-META.XML
  3. Right-click on the file > Properties > Security tab > Advanced > Enable inheritance .

  4. Make sure that 'psaadm' user has Full control permission for the files.
