Plesk error reading /etc/psa/php_versions.json: can not parse php_versions

[vinayakk]

Plesk Panel encounters various errors. For example, Webmail is showing Internal Server Error. Different Plesk utilities fail with an alike error:

# /usr/local/psa/bin/admin --show-password

2013-11-21T12:54:04+01:00 ERR (3)  [util_exec]: proc_close() failed
2013-11-21T12:54:06+01:00 ERR (3)  [panel]: Error reading /etc/psa/php_versions.json: can not parse php_versions_info object : JSON object is expected. Error occured at offset 0, character '\x00'.
Releasing semaphore 27 in request

The same error in Plesk Panel GUI:

ERROR: Service_Agent_Exception
Up Level
Unable to execute php_handlers_control: Error reading /etc/psa/php_versions.json: can not parse php_versions_info object : JSON object is expected. Error occured at offset 0, character '\x00'.

This error usually occurs when '/etc/psa/php_versions.json' is modified or corrupted.

This can be resolved by the below steps

1. Save the original file

    cp -p /etc/psa/php_versions.json /etc/psa/php_versions.json.orig

2. Replace the file from psa-php5-configurator package. You can download the package from Plesk installation repository http://autoinstall.plesk.com/

3. Download the corresponding package by using the proper URL which matches your OS:

For example:-    wget http://autoinstall.plesk.com/PSA_11.5.30/dist-deb-Ubuntu-10.04-x86_64/opt/php5/psa-php5-configurator_1.6.3-ubuntu10.04.build115130724.18_amd64.deb

4. Unpack the file from a package and replace:
