Hey @bastianonm
I wanted to make PRs but couldn’t find a git repo. only svn :/ Would have to set it up just for this.
so i am doing this here:

/wp-gpx-maps-admin.php: line 251 (end of file):

– original: <!– The First Div (for body) ends in the respective file for the corresponding tab –>
– fix: remove html comment from end of php admin file
– reason:
If you use <!— in a php file it will generate output, which is in this case fatal. It will kill all json outputs made by wordpress. (aka Rest calls, auto-save features, medialibary calls,…).
If you want to keep the comment use // within the php tags

/wp-gpx-maps-admin.php: line 178:

– original: $tab = $_GET[‘tab’];
– fix: $tab = isset($_GET[“tab”]) ? sanitize_text_field($_GET[“tab”]) : “”;
– reason: saftey, don’t trust user input, ever..

keep up the good work https://devfarm.it/wp-content/plugins/wp-monalisa/icons/wpml_good.gif
