Content plugins are not applied in Item Description (r1601)

I accidentally installed v1.5.6 RC9b r1601 for J1.5 instead of the last stable version and have some problems now which I'm trying to resolve.

1. All of my templates were removed after the intallation. I have a backup of my old site but I think it's a defect, they should not be deleted after upgrade.

2. Content plugins are not applied in Item Description but they are enabled for the description, text and textarea fields and applied perfectly for Category's descriptions and other text fields except the Item main one.

Thanks in advance for your help.

Deleted templates? the built-in templates DEFAULT,FAQ,PRESENTATION,ITEM_TABBED are always replaced on every upgrade,

or do you mean other custom templates ??

-- please do not modify built-in templates , if you need to modify then duplicate them

About plugin triggering is it all plugins or a specific plugin that is not triggered?

Also check 2 parameters in field configuration of description and re-save it

make sure both parameters "Enable triggering" and you have selected none(=all) or some of the plugins

Thanks for the fast reply.

Yes, all of my custom templates were removed.

About plugin triggering is it all plugins or a specific plugin that is not triggered?

I'm not really sure about triggering in the front end but in the admin area editor-xtd-buttons panel with plugins buttons is absent for main Description of the Item (only). It shows well for all other textareas and for the Description of the Category.

Here are some caps (sorry, I russian locale, because I don't know how to switch the language to English)

Description of the Item: s2.postimage.org/6ukv3s6yf/image.png

Other textarea fields of the Item:
s2.postimage.org/v0viewt2v/image.png

Description of the Category:
s14.postimage.org/aflsw1lfz/image.png

Description Field settings:
s13.postimage.org/yi1m6wq8l/image.png

Upgrading FLEXIcontent does not delete any files in templates folder, only replace built-in templates, so this is strange,

also the bug in editor buttons is an old one and it has been fixed, try re-appling the upgrade (never uninstall , always upgrade or downgrade)

If the problem persists you can send me a PM with admin Login + site URL

Regards

Thanks.

Where can I download the latest version to upgrade (with fixed editor buttons)? I have v1.5.6 RC9b r1601 now installed.

This was fixed some revision before r1000, if it was frontend i would say that maybe you have a template override,

please reinstall r1601 and if the problem persists send me a PM to check for a possible bug (i cannot replicate this problem locally)
