Commander v6.1 File editing not possible

[rogerco]

Have I made a terrible mistake by updating to v6.1.2 on a Joomla 5.4.7 site? It was offered as a standard extension update from 6.0. but now editing any file is not working. The editor window opens but when you click Save I get a yello box at the top of the screen with the message "Save failed with the following error:" in bold white and no further text.
In the console with dev tools inspect is the following message:
==================
"editors.js?45c778:31 Direct access to Joomla.editors.instances is deprecated. Use JoomlaEditor.getActive() or JoomlaEditor.get(id) to retrieve the editor instance.
get @ editors.js?45c778:31
phSaveEdit @ phocacommander.js?45c778:92
Joomla.submitbutton @ index.php?option=com…2RlZmF1bHQucGhw:231
executeTask @ joomla-toolbar-button.js?623aee:119
==================
Save and Close gives the slightly more informative message which I can screenshot but don't seem to be able to paste here (imgur as per your documentation gives a not available in your region error (I'm in GB). The top lines are
===================:
danger
Error - this file type is not allowed
An error has occurred.

Everything was working normally just before the update. I have tried turning it off and turning it on again (TIO&TIOA). The file I am trying to edit is a php one with permissions 644 - which is exactly the same as before the update and was working normally.

I have reinstalled v6.0.o over the top of 6.1.2 and all is fine again. I don't currently have a J6 site to test against but Commander 6.1.2 is broken on J5.4.7

Hi, Phoca Commander does not store any data, so you can easily install the previous working version on Joomla 5 and ithis is all. The only one problem could be the security, the latest Joomla 6 and Phoca Commander solves security problems. So in case you need to run old version be sure, noone other than you can use Phoca Commander on your site.
