joomla 1.5.26 jce update fails with endless loop


Noone does joomla updates and plugins get never ever updated. Hackers have fun with this. If I had got as much time as those ones I would go everytime in the forrest for lumbering. That would be much firewood :-)
Therefore I have to do this :-(

The JCE Plugin had in it’s imagemanager some vluneribilities: - - [29/Mar/2013:01:39:45 +0100] "GET /components/com_jce/css/popup.css HTTP/1.1" 200 416 "-" "libwww-perl/5.836" - - [29/Mar/2013:01:39:45 +0100] "POST /index.php?option=com_jce&task=plugin&plugin=imgmanager&file=imgmanager&method=form HTTP/1.1" 200 36 "-" "libwww-perl/5.836" - - [29/Mar/2013:01:39:47 +0100] "POST /index.php?option=com_jce&task=plugin&plugin=imgmanager&file=imgmanager&method=form HTTP/1.1" 200 36 "-" "libwww-perl/5.836" - - [29/Mar/2013:01:39:48 +0100] "POST /index.php?option=com_jce&task=plugin&plugin=imgmanager&file=imgmanager&method=form HTTP/1.1" 200 70 "-" "libwww-perl/5.836" - - [29/Mar/2013:01:39:49 +0100] "POST /index.php?option=com_jce&task=plugin&plugin=imgmanager&file=imgmanager&method=form HTTP/1.1" 200 36 "-" "libwww-perl/5.836"

After successfull recovery from a clean backup you must to update the JCE Plugin but you’ll get a 500 error caused due to an enless loop.
Simple solution:
First uninstall the joomla jce plugin. Thereafter do this in your joomla installation folder:

find . -name "*jce*" -type f -exec rm {} \;

It removes the languagefiles which are causing the problem:

find . -name "*jce*" -type f

After this installation of the latest JCE works in Joomla 1.5.26

Have fun!
