Template cannot be linked to another template more than once even through other templ

[ermanue]

After update from 1.8 to 2.4 I have a big problem with templates.


I can´t link any template to a host and the error is "Template cannot be linked to another template more than once even through other templates"

I have seen that is a very commun problem, but I haven´t seen any solution yet.

Is very similar to :

Have anyone any suggestion?


Thanks in advance
