Hi!
I have download and installed AllVideos plugin for JCE.
It required the Joomla Mambot AllVideo, and i have installed this:
"plg_jw_allvideos-v2.5.4_j1.0.zip" (the better version for joomla 1.0 i think)

I have "com_jce_111" and "bot_jce_1192"

But, whene i open try to write a new article a javascript alert tell me "Please install the Allvideos Joomla mambot". If i close the alert and click on the little icon to add video, a white javascript windows open whit: "alert('Please install the Allvideos Joomla mambot')"

What have to do?
thanks!
bye bye!

Will you use this allvideos plugin on Joomla 1.5? because it's not compatible with it.
but regarding your problem: it's the editor that's not working, you should install the mambot first.
