Hello
No frontend issues exist however there was 2 backend issues that have been amended with the latest download of each template.
The first issue is regarding the 'Repeatable' field type which is been discontinued by Joomla (
https://docs.joomla.org/Repeatable_form_field_type). This effects some older templates and modules where images are selected within a modal/lightbox window (Eg. Revolve LayerSlideshow module).
The second issue is regarding the 'Subform' field type (
https://docs.joomla.org/Subform_form_field_type). This field requires a simple style fix.
After updating re download your template from your Joomla51 'My Downloads' and re install any templates/modals that are effected by either of the above issues via your Extensions Manager.
