Products screen disappeared (white blank screen when product link is clicked)

[Dominic78]

Hi All, 

I am praying someone here has some advice or a solution to this problem.

 

I have a current working online store. From out of no where an an error has developed that I can not seem to solve, I have trawled the internet for 5 hours and tried a few things I have seen suggested but to no avail.

 

The backend of the shop seems to be working fine with no problems.

 

The Frontend looks fine and you can click through the CMS pages and into categories fine, but if you select any product you just get a completely blank screen (if I inspect source there is nothing there)

 

I have had some customer emails who have tried to go in an order and found the error so I am a little flustered.

 

Can anyone possibly shed any light on this for me please

 

Kind Regards

 

Dom

 

PS. I have also tries creating a new product to see if it would work but I still get the same issue

Please switch error detection on in Defines.inc.php and tell us what error there is.

define('_PS_MODE_DEV_', true);

Ok so I found the culprit, It was  the Product Comments module that has caused the error since it updated the other day i am guessing. 

 

Does anyone know if you can rollback the update somehow? I dont want to loose all of my customer comments

 

Thank you

What I did in a similar situation was to download a compatible version of Prestashop and to overwrite the module directory of my installation with the directory from the fresh install. 

 

But I don't know what your update did to the database connected to the module. If you have a backup your could roll back from there.
