Blank Screens after some Hours

Hello ,

I installed an new opencart shop with only 2 plugins (payment and shipping)
Opencart 3.0.3.2 with PHP 7.2

After some hours the shop is only giving a blank screen.

The error log file gives me this error .

Backend log: PHP Warning: require_once(/home/user/domains/DOMAIN.COM/public_html/vqmod/vqcache/composer/autoload_real.php): failed to open stream: No such file or directory in /home/user/domains/DOMAIN.COM/public_html/vqmod/vqcache/vq2-_home_user_domains_DOMAIN.COM_storage_vendor_autoload.php on line 5\n
Backend fatal error: PHP Fatal error: require_once(): Failed opening required '/home/user/domains/DOMAIN.COM/public_html/vqmod/vqcache/composer/autoload_real.php' (include_path='.:/opt/alt/php72/usr/share/pear') in /home/user/domains/DOMAIN.COM/public_html/vqmod/vqcache/vq2-_home_user_domains_DOMAIN.COM_storage_vendor_autoload.php on line 5\n

Any suggestions or ideas what the problem could be?
Admin Page is also blank
thanks a lot

you installed vqmod so...

Yes I had to for the payment module. Now you mentioned that, it gave me an idea
I cleared the cache from vqmod.

Think there was something wrong as I dont have errors till now.
Going to wait the coming hours and hope the errors dont come anymore.

thnx

Hello,
Sometimes you see blank pages in opencart due to vqmod. Usually it is session error. You need to install a new fresh copy of VqMod whenever change your server. Also replace old index file with newly downloaded (uninstalled) copy of opencart.
To fix opencart blank page,you need to do following steps:
1.Check logs for error,logs are located on following path: system/logs
2.Check if you have corect database detalis on your config.php,this file is located on your opencart root directory.
3.Check if your domain have corect DNS and points to correct server.
4.Check if your mysql server is running
5.Check if you have latest php version.

Mika Hawkins

You may want to use the Integrated VQmod, that one offers a better integration between OCmod and VQmod. In fact, it works more like OCmod, using the same cache.
