Backup/restore option is missing

[cibalibeb]

I recently upgraded from 1.1.9 to 1.2.0/1.2.1/1.2.2 I was going to backup all my data and do a clean install as some of the feature have been broken since upgrading to 1.2.0 when I login to the admin page and go to backup/restore all i get is a blank page, please see the attached screen shot.

I think your upgrade failed at some step to copy all the files.
If you do not have custom files in your store, what you can do is the following:

Take following directories from abantecart cart distribution of your version and copy over your directories completely replacing them.

admin/controller
admin/language
admin/model
admin/view

storefront

code

You might need to do the same for extensions, but if you have some custom extensions, you can not replace extension folder completely
