Hello,

I could not replicate your issue in here. Would you mind to send a simple sample that replicates this issue? Did you place WebTextEditor inside master page or inside page which using master page?

Regards,

Attached is a sample application.

You will see 3 pages.

1master

WebForm1.aspx child of master

default.aspx  Stand alone page.

Default.aspx works fine, but when i use the content page (webform1.aspx) that is where i get the error.

thanks

Hi,

I can replicate the issue in here. It seems XML compression properties caused the issue. I will report this issue to our developer teams. For now, please remove the properties as temporary workaround.

XmlCompressionEnabled="True"
