The URL did not pass strict parsing because of the following error(s): Line 1: Tag section invalid

[HH Services Limited]

Hello everybody,

When running a tool for browsers compatibility, I get the following message:

The URL did not pass strict parsing because of the following error(s): 

• Line 1: Tag section invalid

 

Does anybody know where to locate this tag and how to fix it (how should it look like..)?

 

Thank you.
