Hello,
a few weeks ago we updated 3 sites from joomla 3.9 to 5. On this sites the plugin ignite Gallery is in usage. While two sites with other j51-templates are working fine, the site with the template j51_Valencia has troubles with it's frontend editor.
When using the gallery-Button from ignite Gallery, the modal Popup misses a save-button. It doesn't even appear in the inspectors code. When another template is active, the form works as intendet.
This problem only exists for frontend editing. Using the form in backend works.
