Hi Frank,
Thanks for reaching out.
This issue is related to a compatibility mismatch between Showtime Image Gallery and the Joomla version you are currently running.
Showtime Image Gallery v1.10.0 and newer are not compatible with Joomla 5.3.x.
That’s why pages containing galleries are not rendering correctly.
Quick ways to resolve this
You can fix this immediately using one of the following options:
- Update Joomla to version 5.4.1 or later (recommended), then keep using the latest Showtime version.
- Rollback Showtime Image Gallery to version 1.9.0, which is the last version compatible with Joomla 5.3.x.
After applying one of the above, the affected pages should display normally again.
If you need help with the rollback or upgrade process, let me know and I’ll guide you through it.
Best regards,
Lefteris
