[RESOLVED] Error 500 after migration

[LeSchtroumpf]

Hello,

I recently switch my host because of slowness. I save and transfer my database and the website by FTP.

My website is working when debug mode is activated but i have a 500 error when debug is deactivated. I can't explain why.

Does somebody have an idea ? Did i miss something while migrating ?

What's your prestashop version? It might be that the errors are all in the server's error_log file, you might want to check that, as some servers won't display anything at all, and just log.

[LeSchtroumpf]

The installed version is 1.7.

I had 2 sites to migrate in the new host, i migrate the first one (wordpress site) in the "/public_html" and the prestashop site is in a subfolder "/public_html/MYSITE". When deleting the "public_html/.htaccess" file, error 500 let place to a 404 error.

I'm currently washing my tree to have "/public_html/SITE1" and "/public_html/SITE2". I'll come back if my issue isn't resolve after cleaning (probably yes because i had 404 error).

Thanks for your answer.

Any help would be appreciate.

There is a file/folder permission error - check if the correct access rights are set

[LeSchtroumpf]

I did, but all seems good :

Guess these are not the affected directories. More likley the translation or cache directories.

Try to rename /var/cache to /var/cache_old so that it will be regenerated autmatically with next page call.

You can also run this script, it will check permissions as well:

Oh god, renaming works.

Thanks a lot !

Dear all

Both servers from same hosting provider and they done migration.

After migrate a server I got HTTP ERROR 500

Front office and back office are not working.

Then I enabled error reports using defines.inc.php

After ('_PS_MODE_DEV_', false); Replace it with: define('_PS_MODE_DEV_', true); showing this error report

Fatal error: Uncaught Error: Class 'PrestaShop\PrestaShop\Core\ContainerBuilder' not found in /home/..../public_html/config/bootstrap.php:34 Stack trace: #0 /home/..../public_html/config/config.inc.php(57): require_once() #1 /home/..../public_html/index.php(27): require('/home/..../p...') #2 {main} thrown in /home/..../public_html/config/bootstrap.php on line 34

@LeSchtroumpf

I tried : https://stackoverflow.com/a/21796530

Here is  the report

 

Fatal error: Uncaught Error: Class 'PrestaShop\PrestaShop\Core\ContainerBuilder' not found in /home/.../public_html/config/bootstrap.php:34 Stack trace: #0 /home/..../public_html/config/config.inc.php(57): require_once() #1 /home/..../public_html/index.php(60): require('/home/..../p...') #2 {main} thrown in /home/..../public_html/config/bootstrap.php on line 34

You are running PHP 7.4 -> Prestashop is only compatible until PHP 7.2. - you need to downgrade and allow fopen (php.ini setting or in your webhosting panel or ask your webhoster)

[White Lion]

Dear JBW.

We've changed PHP version to 7.1 and "allow_url_fopen" on.

But same result.

This topic mark as solved and I started a new topic.

Yea, same problem and same way out I used. In all guides how to migrate to new server should be that information included about the /var/cache.
