Hi,
I am new in this forum and its quite big forums so I dont know where to post this, I am sorry if i made any mistake .
I am having problem with my magento, I am using 1.5 version of it, on my local host everything works fine but Now i start working on server, I install magento fine and manage category and everything in normal way but when i put widgets , images or even flash content, Its not working at all.
Widgets can b dragged in editor panel and also images but after saving they are not working, images got broken image link and specially when i add widgets there is error or message "Widget is not specified" some rror like this.

can somebody please tell me how to work out in this???

Regards
