Error deleting product Prestashop 1.6.1.5

[flyclothing]

Just upgraded to 1.6.1.5 and noticed when I delete a product now I get a blank screen.  When I refresh the screen, I get this error.

it seems that the product was actually deleted, but with some error,  so when you refresh, it will show not found because it was already deleted,

you may try to look at error log and see what is the error  (you can check if there is any error log under ffolder StoreRoot/log/, it may give you some hints of the cause.

 

By the way, if your store has other 3rd party modules installed before upgrade, you can also try to remove the following class index cache to see if it fixes the problem.

because during upgrade, it seems it will re-generate class index, but it will not include 3rd party modules override classes in some scenarios.

 

StoreRoot/cache/class_index.php

I dont know if I cleared the browser cookies after upgrading but assume I did.  Rather than going back to the product page once deleted, it was creating a white screen and then I had to refresh to see that error information.

Turn on error reporting before you delete it first, it should tell you what kills the script, exactly

Thanks Nemo.  It seems the issue might have been a mail override from my theme and add-on module.  I am still checking the shop but I disabled overrides and its back to working.  A big thanks to Michael Bellini for isolating the issue.  It was causing orders not to complete but receive payments, no order emails, product modification errors, pdf invoice issues, etc.
