Revo 2.2.4 hangs when saving a resource

@Steve: Yes, have seen that too and upgraded the mentioned site as soon as 2.2.6 was out (in the hope it would solve that issue) but unfortunately it didn't^^...

Still no solution to this bug? I'm experiencing it randomly in various different installations of modx revo, from 2.0.2 to latest, also it happens only on some pages for me: I can use the "rapid" resource modify, but not the normal. Working on chrome dosn't changes anything and I cannot edit some pages of a client site -__-

Holy God,
I've lost all afternoon in deleting caches, updating to revo 2.2.6, changing browser, disinstalling tinymce, but to no avail.
Some (not all, only some, all the resources with an ID over 69) resources of my client's site could be saved only in "fast modify" mode, not in normal mode!! Even if I make a VERY SMALL change, it still hangs-up on save.

Please help!!

Tryed also firefox, safari, chrome, and I cannot even create new pages now!! O__o

Here are the server infos:MODX Revolution 2.2.6-pl (traditional)
PHP: 5.2.17

Edit: It must be a problem of my resource #70, since all resources under that number, new or old, cannot get saved. I got it by duplicating it from another resource, maybe this can help?
I'm going to try to delete it and recreate anew, but I will loose ALL resources inside it and will have to do a LOT of work again -__-

@Erebus - Is there anything significant in the MODX error log? Back to what I mentioned before, are there any TVs only available to Admins?

Erebus, before deleting the resource, drag the children into another folder.

Hello, first of all thanks for the help!
I will try moving resources before deleting, I was first trying to create new resources.
I don't have any TV set up for admin only, the error log reads this:

MODX seems to be looking for areas of the database that don't exist, and plugin files aswell. If you have not already, MANUALLY delete all cache files, re-install TinyMCE (remove completely first) and upload / re-run MODX setup. Let us know what happens.

If you can use QuickEdit, uncheck the richtext field for that doc (and turn off the richtext_default System Setting). The fact that you can save with QuickEdit suggests that it might be a plugin connected to OnDocFormSave or OnBeforeDocFormSave that's throwing an E_NOTICE error because of an upgrade at the server. I suspect TinyMCE, which the error log suggests is messed up.

Next, I would first try disabling all plugins connected to any Doc Form Save events (or just disable all plugins, starting with TinyMCE). You can disable plugins by right-clicking on them in the tree.

As per SteveK's suggestion about the TVs, next try disconnecting all TVs from the template used by the page.

Ok, I tryed all you said:
I deleted the cache from inside modx first, then manually, then I deleted the browser cache.
Disabled richtext in settings and resource, and all plugins (I had only codemirror and tinymce installed), tryed to move childrens out of the directory into the first level of the site and modify then after that, and tryed saving: same hang up.

I then reloaded setup and it got smootly to end, tren tried again after deleting all the caches again: hang up

The errors log shows...empty, no errors :O
I tried to wait about 2 minutes for the page to "save" spinning on "save", but got nothing (of course I controlled after hitting "reload": the page was NOT saved).

I tried to modify another page that didn't showed the problem before: it saved normally.
Error log again empty anyway.

Before disabling the TV (I do it from the template right?) I want to know if that means deleting all the TV values for ALL the site: that would render the parts of the site that are functioning unusable, and it would mean almost remaking the site from scratch O__O

I also tried to change the template of the "damaged" page, to make an empty template with no variables, but after I click "ok" on the dialog, it goes to "saving" and hangsup again -__-
(the browser reads "waiting for answer from server" when the save is freezed).
(again, error log empty!!!)
