Hi
Following these instructions (sort of)
https://www.zen-cart.com/tutorials/index.php?article=98

Created duplicate DB
Copied all files to /new folder
Point config files to new db
/zc_install/ updated DB.. fine all working

Copied 1.5 files over (without deleting 1.3.8 files)

fine all working

Now i was left with a mix of 1.38 and 1.5 files... presumably. Due to template overwrite system etc. Also ZC still using the cache from the old (original folder)

Deleted all files apart from config files.

Copied over JUST 1.5 files.

Now its hanging.. cant get to catalog or shop

The instructions https://www.zen-cart.com/tutorials/index.php?article=98 dont say anything about ever deleting the old files just copying new ones on top.

Its just hanging... i remember before for something i used a fix cache key.. buy its been removed now

What can i do?
