Thread:Extension talk:ConfirmEdit/The current version of this extension is not compatible with 1.20/reply (5)

I found the source of the problem: the source was me.

For some unknown reason in previous installation I've configured FancyCaptcha right in the extensions/ConfirmEdit/FancyCaptcha.php file and while upgrading I've replaced all my custom configuration with a default one. So nothing worked.

So there is no bug in FancyCaptcha in my case (what about Prh47bridge's case I do not know), but there is a wish requests

1. to add some more diagnostics in cases when capcha files are missing or wrong

2. May be do some sanity check on initialization, i.e. check that capcha dis exists or something, so when you run media wiki on wrong configuration you will get warning even when you are not editing anything. May be add this check to upgrade script if it is possible...
