I have changed my server to new one and I get this error when I try to open website front office or BO. I can't understand what's going on. My cache is disabled but I can see app/cache/prod folder. I don't even have app/cache/dev folder and I can't understand why system are looking for it (I deciding it by this error) Does anyone have idead how to fix it? Thanks in advance

Additional information

Hi @ArnasL,

To move a Project to a new domain without errors, please follow these steps:

1. made a backup for my files & my database
2. upload my store's files to your new server
3. import the old store's database to the new server
4. In file /app/config/parameters.php, configure my PrestaShop site.
   4.1. DB_SERVER: database's server;
   4.2. DB_NAME: Name of the database from step 5;
   4.3. DB_USER: User associated with the database;
   4.4. DB_PASSWD: The user's password;
5. in Table ps_shop_url, change with the
   5.1. domain => new domain
   5.2. domain_ssl => new domain_ssl
   5.3. physical_uri => new physical_uri
6. clear the cache manually by deleting all the folder into app/cache (prod & dev).

=> OK => no problems.

Thanks to check & feedback.

Hi @khouloudbelguith

looking here:

_Fatal error: require_once(): Failed opening required '/var/www/MYDOMAIN.COM/public_html/app/cache/dev/appParameters.php' (include_path='/var/www/MYDOMAIN.COM/public_html/vendor/pear/pear_exception:/var/www/MYDOMAIN.COM/public_html/vendor/pear/console_getopt:/var/www/MYDOMAIN.COM/public_html/vendor/pear/pear-core-minimal/src:/var/www/MYDOMAIN.COM/public_html/vendor/pear/archive_tar:.:/usr/share/php') in /var/www/MYDOMAIN.COM/public_html/config/bootstrap.php on line 86_

I think this is clearly a cache issue !

@ArnasL
You can just runin your root prestashop site folder :

_php -d memory_limit=-1 ./bin/console cache:clear_

[khouloudbelguith]

@PululuK, yes!
It is the last step: clear the cache manually by deleting all the folder into app/cache (prod & dev).

Thanks!

The domain is the same, just a new server. I have deleted prod cache (dev doesn't even exist). I think this problem is related to permissions. Because I can't see cache/dev folder. Also missing /var/ folder. Does anyone can guide me how can I fix it?

Hi @AAymeric
Sorry man !
For your Pretashop version you must use :
_php -d memory_limit=-1 ./app/console cache:clear_

[khouloudbelguith]

@ArnasL,

Also missing /var/ folder. Does anyone can guide me how can I fix it?

For your PrestaShop version, the var folder doesn't exist
https://github.com/PrestaShop/PrestaShop/tree/1.7.3.0

Thanks!

Getting this error now:

[Symfony\Component\DependencyInjection\Exception\RuntimeException]
Cannot dump definition because of invalid class name (NULL)

[ArnasL]

Ok, but I still think prestashop can't create new files and folders after migration, how to recheck these privileges?

@ArnasL,

[ArnasL]

@PululuK anyway something happend after that line of code. Now I can see in FO maintenance mode On and in BO I see new error:

Whoops, looks like something went wrong.
1/1 RuntimeException in bootstrap.php.cache line 2802: Unable to write in the logs directory (/var/www/mydomain.com/public_html/app/logs)

[khouloudbelguith]

@ArnasL,

If you don't have access, you can check with your host to give the right permission.
Give the write and read access.
$ chown -hR www-data:www-data ./Project_Folder_name
Some hosts might require you to useCHMOD 777, although it is not recommended for anything more than a one-time need.
If you have to use CHMOD 777, make sure to switch to a safer setting (for instance, 775 for folders and 664 for files) once you are done upgrading.
Thanks to check & feedback.

[ArnasL]

Almost everything is fixed now. Thanks for everyone for help! Last thing which is not working, friendly SEO urls. Trying now debug this
I also changed my PHP version to 7.0 from 7.2 because of a lot of incompatibility.

[ArnasL]

mod_rewrite is enabled I don't have any idea why it's not working
Here is my presta info

[khouloudbelguith]

@ArnasL, mod_rewrite is a useful Apache module that can be used effectively to ensure human-readable URLs.
First, we need to activate mod_rewrite. It’s available but not enabled with a clean Apache 2 installation.
sudo a2enmod rewrite
You need to change the default Apache configuration file

<VirtualHost *:80>
    <Directory /var/www/html>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </Directory>

    . . .
</VirtualHost>

For more details, thanks to check with your host and feedback.

[ArnasL]

Yes, now all good, problem solved. Thanks

[khouloudbelguith]

@ArnasL, thanks for your feedback.
Since it is fixed, I close the issue, feel free to open a new one when needed.

Thanks!
