After updating, cannot connect to back office!

[aid-a]

After updating prestashop to newest version, I discovered that my back office look like this. Backup doesn't work... same thing.
HELP!!!

thanks!

[shokinro]

Please set _PS_MODE_DEV_ to true in file  /config/defines.inc.php  and then page again to see what is the error message displayed.

it will give you some hint what was the cause so that you know what to do.

if (!defined('_PS_MODE_DEV_')) {
define('_PS_MODE_DEV_', false);
}

[aid-a]

Nothing happens... I already used this kind of operation but now it does not work

[shokinro]

have you checked error logs

1. at back office - Advanced parameters - Logs tab

2. folder StoreRoot/log/

[aid-a]

I don't know how to check these errors, Shokinro. I have no knowledge in it. 
The only error it have me:

Fatal error: Call to undefined method Link::matchQuickLink() in
/home/indecori/domains/indecori.com/public_html/tools/smarty/sysplugins/smarty_internal_templatebase.php(157) : eval()'d code on line 341

Thank you very much for your help, I really need it!

have you tried to delete following cache file? it might class index was not generated correctly.

/cache/class_index.php

[aid-a]

Deleted /cache/class_index.php  file, and still nothing... Doesn't work
Maybe at this moment I should change _PS_MODE_DEV_ to false again?

[shokinro]

really have no idea, how this Link class not loaded, I doubt your store upgrade might be not successful.

 

can you check if following file exists or not, if it does not exist, please try to copy from prestashop original package

 

/classes/Link.php

Edited April 22, 2016 by shokinro (see edit history)

[aid-a]

Thanks Shokinro, But I haven't found this file in the folder. Where should I download it? Where is prestashop original package?

[shokinro]

Sorry, it wrote Wong path, the original Link.php gile should be under /classes/ folder, not under override folder. I have corrected it in my original post too.

Edited April 22, 2016 by shokinro (see edit history)

[aid-a]

In that folder still I cannot find this file. So where I can download it? Thanks! because I really have no idea how to do it.

[shokinro]

If you following file does not exists you can download the same version of Prestashop package from prestashop.com and then copy the same file from the same folder of the package

 

 

YourStoreRoot/classes/Link.php

[aid-a]

Yay it worked! Now I have access to my back office, but as I still have not changed true to false, it gives me million errors. Could you please look if it means anything bad? Thanks a lot!

[shokinro]

from the error message, there seems still some problems with some of the links.  

I guess there might be some other files kissing. how about copy the whole folders of following from the prestashop package to your store and then try again.

(Please the use same version of PrestaShop package you are using)

 

/class/

/controllers/

[aid-a]

Unfortunately I downloaded more recent version file Link.php, my prestashop version is 1.6.0.9 and in prestashop.com it's 1.6.1.5... I found my prestashop version files. Which files should I change? It won't affect my theme, my products etc?

Edited April 23, 2016 by aid-a (see edit history)

[shokinro]

you have to download the same version of PrestaShop.

please use attached - it is from 1.6.0.9, - please rename it first.

 

Link.php.txt

I found my version link.php file and back office doesn't work. So the problem is in updating? How should I update to recent version? I should reuse link.php of more recent version and use one click upgrade? 

[shokinro]

if you have upgraded to new version, then you have to use the Link.php file from the new version, it must matches your store Prestaashop current version.

 

But I am afraid if the upgrade is not done properly, that might be not the only file. If that is the case, I would suggest you restore your store from backup and redo the upgrade.

[aid-a]

Crazy, but my previous backups of my store disappeared, I have only 2 backups that dont help me - BO doesnt work. You know, these problems appeared when I chose automatic updates in my server (in instalatron).
The only way I managed to make my BO work is to put "link.php" of newer version. I know I shouldn't do like this. And when I try to go to module's section, it doesn't open. I just wanted to do one click upgrade. It makes this error: 

• [PrestaShop] Fatal error in module smarty_internal_templatebase.php(157) : eval()'d :
  Undefined class constant 'MODE_HOST'

My question is: is there any way to save my theme's layout and translation and everything, make an update and import some theme's files to ftp? I dont want to lose several weeks of work when I translated all the theme to my language, and making the layout I like...

 is there any way to save my theme's layout and translation and everything, make an update and import some theme's files to ftp

 

 

 

I do not know about your theme.

But for translation, you may be able to export from back office - Localization - Translations - Export A Language section.
