Found the solution.

Problems come from phrases and variables.

You have to replace in x_replied_to_a_thread_y_in_z in GLOBAL, this

<a href="{1}">{2}</a> replied to a thread <a href="{3}">{4}</a> in <a href="{5}">{6}</a>

with this :

<a href="{1}">{2}</a> replied to a thread {4} <a href="{3}">{5}</a> in <a href="{6}">{7}</a>

In x_started_a_thread_y_in_z of GLOBAL, this :

<a href="{1}" class="username">{2}</a> started a thread <a href="{3}">{4}</a> in <a href="{5}">{6}</a>

with this :

<a href="{1}" class="username">{2}</a> started a thread {4} <a href="{3}">{5}</a> in <a href="{6}">{7}</a>
