Before you began to yell to me let's be clear: I'm aware, that this is an evergreeen question there. I have read all the relevant posts, the manual, the tips and tried out each and every solution proposed. I'm not a newbie - building multilangual websites with this component since old Mambo/Mambelfish days (more, than 50 such sites are on my portfolio), and I'm running the joomla-tips dot org site, so, supposedly I know a thing or two about this world. And had never meet this problem...
Recently I was hired to fix a Joomla site built by someone else, and one of the problems is this stupid error message on the respective module position. I checked and doublechecked, all plugins are there, are enabled, System - Jfrouter plugin was edited, have the correct content and it's saved. I tried to uninstall/reinstall the component, downgrade to earlier release, etc. but I'm still clueless on what's happening.
Here are the crucial system data:
1. Joomla 1.5.14
2. Joomfish 2.0.4
3. PHP Version 5.2.10
4. Webserver Apache/2.2.13 (Fedora core: 184.108.40.206-64.fc11.x86_64 #1)
5. MySQL 5.1.40-log
6. memory_limit 32M
What may be counting there as potential problem: site has tons of components/modules/plugins (in my opinion none should cause this problem), from relatively common things, like VirtueMart and sh404SEF, and some rarely used, as User Alpha points. I've used all the components up there using JoomFish -but not this exact mix on the same site - but never had this particular problem with any of them.
Ahh, allmost forgot: the two Joomfish related system plugins are there in the right order, as supposed to be, prior the other system plugins, having orders number -101 and -100, as they are installing by default. Any clues on what may be the cause are welcome!
PS. I have at least 6 sites running the latest JoomFish/Joomla combo, withouth a hitch. Great work, guys, I'm a fan of the Fish sice his first launch - I build multilang sites since 1995, so I can appreciate the exceptional value this brilliant componet adds to Joomla world!
