Random Errors - 500 Internal server error

[christinik2011]

Hello. I have this random error. Browsing through the backoffice, preparing orders, going into modules panel, updating tracking numbers..... allmost everywhere, not allways, it is just random, appears when it wants, where it wants, sometimes even in front office. But with a refresh of the page, it goes away and the website performs the previous action.

 

Could someone help me on this ? It is really getting on my nerves since i cannot figure out from where it is.

My prestashop is 1.6.1.10

 

 

In Apache i get this error on the log page:

Premature end of script headers: index.php, referer: http://www.arreglatelo.es/admin*******/index.php?controller=AdminDashboard&token=df87687963948e3e55bf2221cee281b5

 

And this is the 500 error:

GET /admin********/index.php?controller=AdminModules&token=1718cbead2a3104ea4dea74fb17daf00 HTTP/1.1

 

Or this for example:

POST /admin*******/index.php?controller=AdminOrders&id_order=13523&vieworder&token=689e3f84e24ee17bf4fd3bee85d4faf4 HTTP/1.1

It could be timeout. Perhaps 30 seconds. See it at http://www.arreglatelo.es/admin*******//index.php?controller=AdminInformation

It's not that, timeout is sed at 3500

Hi,

Do you find any solution for that error? Have the same problem...

[tuk66]

I have seen many times that PHP timeout is ignored or another server timeout is applied.

I have solved my problem - in my casae it was a license for a few modules. The license was submit on workdomain. After domain change to main, license was not correct. It was a reason why I see INTERNAL SERVER ERROR in few sites at backoffice.

I'm just wondering which modules require a license?
