Pages in Plesk return Internal error: Failed to parse metadata, File aps_php.php

1. Connect to the server via RDP.

2. Download the script restore-cache.ps1.

3. Right-click on it and select Run in Powershell.

1. Connect to the server via SSH.

2. Download the script:

   # wget https://github.com/plesk/kb-scripts/raw/0ead0b7853b2e795d0918709f990ba73f7f51a9d/restore-aps-cache/restore-cache.sh

3. Make it executable:

   # chmod +x restore-cache.sh

4. Run the script:

   # ./restore-cache.sh

If the issue persists after 10 minutes, do the following:

1. Clear the Apps cache: Tools & Settings > Application Vault > Clear Cache

2. Create the reported directory if unable to clear cache and retry:

   # mkdir /usr/local/psa/var/apspackages/apscatalog7R2ZJ5.zipb17fa7a9-c64e-c0
   # chown -R psaadm:psaadm /usr/local/psa/var/apspackages/apscatalog7R2ZJ5.zipb17fa7a9-c64e-c0

3. Make sure that SQL query debug is disabled in config file /usr/local/psa/admin/conf/panel.ini.

   The script does not work with enabled debug.

4. Login to the MySQL server:

   # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin apsc

5. Determine metafile_uri path by using the following sql query:

   MYSQL_LIN: mysql> select `id`, `name`, `version`, `release`, `metafile_uri` from apsc.aps_package;
   +-----+-----------+---------+---------+----------------------------------------------------------------------------------+
   | id | name | version | release | metafile_uri |
   +-----+-----------+---------+---------+----------------------------------------------------------------------------------+

   | 77 | WordPress | 3.3.1 | 4 | /usr/local/psa/var/apspackages/2abd12d2-7017-46ee-a80b-ed42599f7c0a/APP-META.xml |

   +-----+-----------+---------+---------+----------------------------------------------------------------------------------+
   3 rows in set (0.00 sec)

6. Make sure that the metafile_uri directories exist on the server.

   Directories should exist as below:

   # ls -la /usr/local/psa/var/apspackages/c22666c4-b469-4eb2-a0e7-7c6f3f4f11eb/APP-META.xml
   -rw-r--r-- 1 psaadm psaadm 50828 Mar 12 21:23 /usr/local/psa/var/apspackages/c22666c4-b469-4eb2-a0e7-7c6f3f4f11eb/APP-META.xml
   
   # ls -la /usr/local/psa/var/apspackages/556229a0-5008-41b5-83d1-3c0b32649196/APP-META.xml
   -rw-r--r-- 1 psaadm psaadm 21506 Mar 12 21:23 /usr/local/psa/var/apspackages/556229a0-5008-41b5-83d1-3c0b32649196/APP-META.xml
   
   # ls -la /usr/local/psa/var/apspackages/2abd12d2-7017-46ee-a80b-ed42599f7c0a/APP-META.xml
   -rw-r--r-- 1 psaadm psaadm 21706 Mar 12 21:23 /usr/local/psa/var/apspackages/2abd12d2-7017-46ee-a80b-ed42599f7c0a/APP-META.xml

7. Make sure that all the APP-META.xml files are readable:

   # head /usr/local/psa/var/apspackages/a1a41e6f-f5ae-4f80-8e30-788a0a418196/APP-META.xml
   
   <application packaged="2014-12-19T14:05:21" version="1.2" xmlns="http://apstandard.com/ns/1">
   <id>http://wordpress.org/</id>
   <name>WordPress</name>
   <version>4.1</version>
   <release>74</release>
   <homepage>http://wordpress.org/</homepage>
   
   <vendor>
   <name>WordPress.org</name>
   <homepage>http://wordpress.org/</homepage>

If it is not readable or binary, remove and recreate the package folder as listed below.

1. If the metafile_uri directory is missing, create it:

   # mkdir /usr/local/psa/var/apspackages/c22666c4-b469-4eb2-a0e7-7c6f3f4f11eb
   # mkdir /usr/local/psa/var/apspackages/556229a0-5008-41b5-83d1-3c0b32649196
   # mkdir /usr/local/psa/var/apspackages/2abd12d2-7017-46ee-a80b-ed42599f7c0a

2. Download APS packages with the corresponding name and version from dev.apsstandard.org to the directories created in the previous step. If your WordPress version is not present on the above mentioned page, visit apscatalog.com .

   Upon downloading via browser nginx 403 Forbidden error can occur. In that case copy generated link to the archive from the browser and download it using wget tool, e.g.:

   # wget https://apscatalog.com/storage/wordpress.org/WordPress/2.7.1-2/parallels.com/undefined/undefined/undefined/WordPress-2.7.1-2.app.zip

3. Extract the zip file in the same directory, for example:

   # ls -la /usr/local/psa/var/apspackages/2abd12d2-7017-46ee-a80b-ed42599f7c0a/
   
   drwxr-xr-x 5 psaadm psaadm 4096 Jan 17 2013 ./
   drwxr-xr-x 15 psaadm psaadm 4096 Sep 5 04:34 ../
   -rw-r--r-- 1 psaadm psaadm 13434 Jan 17 2013 APP-META.xml
   drwxr-xr-x 2 psaadm psaadm 4096 Jan 17 2013 htdocs/
   drwxr-xr-x 2 psaadm psaadm 4096 Jan 17 2013 images/
   drwxr-xr-x 2 psaadm psaadm 4096 Jan 17 2013 scripts/

4. Change permissions to psaadm:psaadm on the package folder recursively:

   # chown -R psaadm:psaadm /usr/local/psa/var/apspackages/2abd12d2-7017-46ee-a80b-ed42599f7c0a/
