[mdusamaansari]

Hi Techies,

 

I am using prestashop version 1.5.4.1

 

I am in need of upgrading it to version 1.5.6.2 (minor release) by using 1-Click Upgrade. My 1-Click Upgrade module is updated to latest version.

 

While upgrading on prestashop, I got this error. I tried twice, I got same error twice.

 

[Ajax / Server Error for action backupFiles] textStatus: "error " errorThrown:"Internal Server Error " jqXHR: " "

 

I have checked my error log files from my server. The error log shows fatal error. The errors are in below.

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 68 bytes) in /var/www/xxxxxxxxxxxxx/modules/autoupgrade/AdminSelfUpgrade.php on line 3656, referer: http://xxxxxxxxxxxxx/manager/index.php?controller=adminselfupgrade&conf=6&token=4c3ba991cd8804fd5cdce66222379796
