Hi Amelia,
A similar problem was reported for WeGlot translator, and I see that the issue is almost identical with this one.
Unfortunately I cannot do anything to prevent that, the translator plugin is automatically translating the whole ajax response text, including the delimiter characters, and the search therefore is not able to parse the response correctly.
If there is a feature within that plugin to add keyword exceptions or something like that, then please add the following keywords:
!!ASPSTART_HTML!!, !!ASPEND_HTML!!, !!ASPSTART_DATA!!, !!ASPEND_DATA!!
Also, there is JSON structure within some of these delimiters, that should not be translated either.
