i use JCE image manager extended plugin to create thumbnails in articles.
But i found that this thumbnail creating function can not be performed in slave sites, but ok for master site. that bothered me much. can you find the solution for me ?

you can try putting images in the articles from frontend with

user: *******
password: ********

master site: www.twlizard.com/twlizard/
slave site: www.twlizard.cmo/twlizard/multisites/life/

please push the "image manager extended" button on the editor toolbar to insert image and create thumnail (the icon is a picture with a small star in the lower right corner)

I am not a JCE specialist.
Give me detail scenario on how to reproduce what you have described.
Screenshot, menu option, video, ... whatever that explain in detail how to reproduce it.

because the error message window is a popup one, i can not use screen capture software to take a snapshot.

would you please log in from the frontend and post a new article and insert a image in both master and the slave site, you will find, you can created a thumbnail in master site, but not slave site.

why i am quite certain about your software is related to the problem is because i recreate a new slave clean site and install jce editor, the condition is the same.

thank you very much, dear edwin

you are the most responsible man i have ever met since i used Joomla.

Sorry but I am unable to do what you tell me.
When I go on your front-edn, the menu are not readable and I don't know how to post the article.
I have tried to clik on the ENGLISH flag to have a readable webpage but this does not give me something that I can read.

In general, it is advised to keep the standard Joomla directory structure when you deploy a slave site into a specific directory.
In your case you have deploye the slave site into {stie_dir} and normally, you should let the image and Media folder in
- images
and
- images/stories

In your case, I have saw that you have specfied another directory for the image and media folder.
In addition, I suspect that you have link on the image and media folder.
They are not specific to the slave site.
