I'm using the nop 4.2 without source code version, and try to use the PayPal Express plugin that is only updated to 4.1.
I made a terrible mistake here: I extracted the 4.1 folder out of the plugin zip, put into the plugin folder of nop, and modified the .json file and changed the 'supported version' from 4.10 to 4.20 manually. Then I went into the local plugin tab in administration and found it and clicked 'install'.
I now know I shouldn't have done this and this is a huge mistake, especially when I forgot to back up my site up before I do this risky experiment.
Please help...how can I roll back to the previous state which has the plugin now installed? I don't know any time travelers or time magician around me...
Or, is it possible to find the files that this PayPal Express plugin changed, and manually replace them with the files from original nop 4.2?
Any help is appreciated, thank you in advance (cry)
The current state of the site displays this error:
