504 error - Server Overload

[pedluis]

Good evening, 

i'm having a lot of problems with my site. Since last 3 days my site is going down (504 error gateway timeout). From hosting told me that they are unabled to find the error.

 

Anyone can help me or has any idea of the problem?

 My version of prestashop is 1.6.1.4

And the server data:

Informazioni sul server Linux #13 SMP Tue Mar 15 13:23:00 EET 2016 x86_64

Versione software server Apache

Versione di PHP 5.6.22

Limite memoria 768M

Tempo di esecuzione massimo 0

can you check the Timeout directive in your httpd.conf file ? seems like your site is getting too long time to respond.

[pedluis]

Thank you shyaminayesh, unfortunately I had a shared hosting with siteground. How can I check those parameters?

[shyaminayesh]

seems like your site need more resources than your current hosting environment or your site is having some issues. o.O guess you have cPanel, can you check the resource usage ?

[pedluis]

Yes I have cpanel. And that was the reason. I have an erp that works using web services of prestashop and it was taking a lot of resources. Now seems to work better.

seems like it's time to upgrade your server ...
