fatal error

[kreik]

Hello.

My prestashop display fatal error. I did 1click update but everything worked fine just after 2 weeks i could not access back-office and front-office also did not work as it should. I checked folders permissions and also .htaccess.I am not very advance in this matter so please if you can help me somehow.

 

Version. 1.6.1.11

 

Back-office error:

Fatal error: Call to undefined function smarty_modifiercompiler_string_format() in /nfsmnt/hosting1_2/9/a/9aa99cb5-3e99-4853-a87f-6beb58792411/ceremonyshop.sk/web/tools/smarty/sysplugins/smarty_internal_compile_private_modifier.php on line 78

I resolved problem on front-page by replacing file Atributes.php from fresh installation but my problem on back-office still persist. And also i found that other pages doesnt work on front-page for example: http://ceremonyshop.sk/login?back=history also trow fired error but after rewrite with fresh file problem disappeared. What could cause this problem?

 

Additional:

I replaced whole folders

-classes

-controllers

-tools

 

And somehow everything seem to work fine. I really dont understant it how can this happen. it wasnt after update but after 2 weeks. 

 

-----------------------------

 

One more update. I found out that files whick cost me a problem work fine when i just coppy them from my ftp to my computer and rewrite them. What could cause this problem? CHMOD rulles are same.

 

----------------

 

Finally i resolved whole problem by setting PHP version from 5.5.21 to - 5.6.5.
