- Presentation file: .pptx, originally created in PowerPoint (custom template)
Hi everyone !
First of all, thanks so much for the amazing work you’re doing with OnlyOffice !
Issue
- In this specific presentation, the command Insert > Slide Number > Slide Number + Apply to all does not display any numbers on the slides.
- Even when editing the master slide (View > Slide Master) and attempting to add numbering, nothing appears.
Tests Performed
- Created a blank ONLYOFFICE presentation → numbering works correctly (numbers appear as expected).
- Applied significant zoom + changed theme → no numbers visible in the problematic presentation.
- Verified the master slide:
- The original PowerPoint master did not contain a number field.
- Adding a placeholder in the master and reapplying Insert > Slide Number had no effect.
- Saved under a new name, converted format (re-saved as .pptx) → no improvement.
Expected Behavior
-
The Insert > Slide Number > Apply to all command should work on presentations imported from a PowerPoint template,
or -
At minimum, ONLYOFFICE should be able to add a number field to the existing master after import.
File
- I can provide an anonymized example file if needed (the problematic PPTX template).
