Hi

Is it possible to ugrade opencart 1.5.5.1 to 1.5.6.4

I am trying to do it on my server so nothing happens to the customer site, I have got the database imported and that seems ok as has imported all the categories, products, customers and orders etc but when on the front end when click on a product, it's a blank page and when on the admin side when click edit to edit a product, the same happens just get a blank page

Any ideas, is there database changes between 1.5.5.1 and 1.5.6.4?

Thank you in advance

Kind regards

Ian

What is your admin - > systems - > error logs indicates regarding the route name you clicked on, either from the admin or store-front end?

Hi straightlight

Thank you for the reply, appreciate it

The error log in the admin side shows the following

Looks like there's either still a missing controller file or a misleading controller file title. The controller module class must be defined with the right location. A simple typo could generate this error.

Also is not showing up in the list of modules in the back end, all I can think is that that extension is not compatible with 1.5.6.4

Apply the same process; viewing the error logs for each events. This will guide you to the right direction on knowing why exactly these blank pages events occurs. :)

Extensions / modules loading methodology should be the same since OC 1.5x releases. This issue you're reporting might be related to another issue.
