joomla 1.5.26 jce update fails with endless loop

Hi

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 πŸ™‚
Therefore I have to do this πŸ™

The JCE Plugin had in it’s imagemanager some vluneribilities:

2.185.154.218 - - [29/Mar/2013:01:39:45 +0100] "GET /components/com_jce/css/popup.css HTTP/1.1" 200 416 "-" "libwww-perl/5.836"
2.185.154.218 - - [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"
2.185.154.218 - - [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"
2.185.154.218 - - [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"
2.185.154.218 - - [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
./language/de-DE/de-DE.com_jce_browser.ini
./language/de-DE/de-DE.com_jce.ini
./language/de-DE/de-DE.com_jce_advlink.ini
./language/de-DE/de-DE.com_jce_media.ini
./language/de-DE/de-DE.com_jce.xml
./language/de-DE/de-DE.com_jce_paste.ini
./language/de-DE/de-DE.com_jce_spellchecker.ini
./language/de-DE/de-DE.com_jce_imgmanager.ini
./language/de-DE/de-DE.com_jce_caption.ini
./administrator/language/de-DE/de-DE.com_jce.ini
./administrator/language/de-DE/de-DE.plg_editors_jce.ini
./administrator/language/de-DE/de-DE.com_jce.menu.ini

After this installation of the latest JCE works in Joomla 1.5.26

Have fun!
