Hey there,

I have SimpleCart installed and when I try to edit one of the Resources named category (see attached screenshot) I end up on a blank page. I can create a new category under the Resource tab and when I do I get the pop-up interface where I can edit said resource but once I hit save and try to edit it again -> blank page.

All other resources or chunks, snippets, etc. work totally fine.

Here's what I've tried so far (without success):
- clearing cache and cookies
- reinstalling SimpleCart
- uninstalling all other extras (and I don't have TinyMCE which seemed to cause similar problems in the past)
- rerunning modx setup

Worth noting might be that when I uninstall SimpleCart I get a few errors (full error log attached):
```
Could not load class: scCategoryResource from mysql.sccategoryresource.
scCategoryResource::loadCollection() is not a valid static method.
PHP warning: Invalid argument supplied for foreach()
Could not load class: scProductResource from mysql.scproductresource.
scProductResource::loadCollection() is not a valid static method.
PHP warning: Invalid argument supplied for foreach()

Could not load class: scCategoryResource from mysql.sccategoryresource.
Could not load class: scProductResource from mysql.scproductresource.
```
My setup:
- ModX 2.6.5-pl
- "hardened ModX" (like shown here:https://docs.modx.com/revolution/2.x/administering-your-site/security/hardening-modx-revolution)

I hope someone can help me with this, not sure what else I could do here.
Maybe the error-log helps? I don't know really how to interpret those outputs.

Thanks alot in advance!

Well, I don't know what the problem was exactly, but a total new installation fixed it. I guess something during the upgrade process to Version 2.6.5 messed things up before.
