[SOLVED] Activities deleted

Hello,
A BIG issue I faced today :
While deleting a project with 9 activities attached, Projeqtor asked the confirmation to delete the 9 activities related (ok, normal behavior) but it deleted also the whole set of activities whatever the project except 1 activity (why this one in particular !?).
here below the structure of the project to delete






Done it twice to control (with a backup), each time the same results with the deletation.

Browser : Firefox 29.0.1
Version : ProjeQtOr V4.2.3, windows server with mysql

Do you mean it deleted activities that sould not have been deleted ?
(it is not clear in the screenshots)

That's it,
expected : 9 activities linked to the project to be deleted
Issue : ALL the activites of the database deleted (more than 300), whatever the project, except 1 activity.

sorry for the screen shots, I wanted to show the original structure of the project / activities to be deleted.

Is it an activity that should have been deleted ?

No, the one activity remaining was out of the project deleted,
In both my tries, it was the same activity remaining, though the databases were not exacly the same (the backup had less records)

Could you check log file for errors are report them here ?

No error risen in the log file at both tries. only the trace of logging.

The first time, The screen "freezed" after the confirmation of deleting the project and activities. I closed ff and relaunched and discover the results of deletation (only 1 activity remaining)
after restoring the backup, I chose the same project to delete and after few seconds of work the screen show back the project list but the database contains only one activiy left, the same as the first time.

Sorry,
In the file : projeqtor\files\config\parameters.php



I added the line : "$debugQuery = true;" but nothing appeared in the log file when I delete the project,
I tried also "$debugQuery = 'true';" without success either.

Only the --TRACE-- are written in log file.
