Upgrade top horizontal menu prestashop 1.5.6 site crash

[shopaccesorii]

Hi all, I've upgraded some of the modules and after upgrading top horizontal menu every page i open is blank, also if i open the configuration for the module it appears the following error:

[PrestaShop] Fatal error in module blocktopmenu:
Call to undefined method Category::getNestedCategories()

 

Is there a method to restore the original module, please help!

Silviu

 

 

edit: i,ve done it, sorry for just asking, but if someone has this problem, it can be solved by replacing it with the original top horizontal module from 1.5.6 by ftp.

cheers

Try uninstalling the module first, if possible, then delete the folder and re-upload a 1.5.6 one. Upgrading 1.5 modules is a bad idea at the moment, as they will be replaced by 1.6 versions that contain new methods

I've done it, found an original 1.5.6 version of module and just replaced it with the upgradet one.

Thank you Nemo, like your tutorials by the way
