On a centos7 webserver with webmin/virtualmin controlpanel installed we experience the following error in two of our hosted prestashops:
Both websites are using an erp system. One hosted in the same server and one on another server. But, both are having the same problem with the same behavior.
All started as this specific webserver had increased load, due to a lot php-cgi processes spawned. All hosted domains (5) were using FCGId as php execution mode. We decided to switch to php-fpm.
After successful switch to fpm, customer informed us that the imported products from the erp systems are being imported without a product image.
there is a custom prestashop module integrated with the customer's erp system. Customer add the product on the erp software and then the product is imported to prestashop.
Now, for some reason, after switching to fpm, product is imported but without the product image.
Developers spend 48+ hours of investigation but without any luck.
We need an experienced engineer to investigate this problematic scenario
