Thanks for having a look. When editing a project you will see

Title
HTML is allowed

Perhaps during later versions this has been forgotten?

I also found a very simple workaround: Only change the datastore-cache entry! Since 'title_clean' will always be taken from there. It's much easier to step-by-step-debug admincp/project.php than all those front end-files

Now 10:37 PM here... good night!

Solution
O.K. here my workaround for all who like it:

Replace every 'title_clean' with 'title' in project.php and projectpost.php, since they all affect only the navbits.

Then replace

            $this->set('title_clean', htmlspecialchars_uni($this->pt_project['title']));

with

            $t = $this->pt_project['title'];
            $i = stripos($t,'<');
            if ($i) {
                $t = substr($t,0,$i);
            }

            $this->set('title_clean', htmlspecialchars_uni($t));

in includes/class_dm_pt_project.php to cut off everything after "<" (e.g. "<a href=...") or change whatever you want.

To see it in action: Project Tools - Forum (see the Icons in the Navbits to change visa versa)

And: Thanks for "Project Tools"!
