Frequently Asked Questions
Why do my PDF form fields show up as untagged in the accessibility checker?
This happens when a form field exists as a visual annotation on the document but lacks the underlying structural accessibility tag. It must be manually tagged as a 'Form' element in the Tag Tree to resolve the error.
How can I check my current PDF software version?
You can check your current version by opening the application, clicking on the 'Help' menu at the top, and selecting 'About'. This will display your exact build and version number.
What should I do if resetting preferences does not fix the Reading Order panel?
If resetting preferences fails, the document itself may be corrupted. Try opening a different PDF to confirm. If the issue is specific to one file, you may need to flatten the PDF and recreate the form fields from scratch.
Can I use WPS Office to fill out and sign PDF forms?
Yes, WPS Office includes a fully featured PDF editor that supports reading, filling out, and signing standard interactive PDF forms natively.
