Fix 1. Clear Cache for Adobe App
Cache clearing depends mainly on the OS version being used. Use the Command Prompt on Windows to access and delete the Acrobat folder from the AppData folder under your user account. Or follow the steps below:
- Close Adobe Acrobat.
- Go to the application directories or folders to find the cache files.
- Delete all cache contents to remove annoying remnants.
- Restart Acrobat and try signing the document again.
Fix 2. Fix Permission Failure
Ensure file permissions permit editing or signing of the forms.
On a Windows Computer:
- Right-click the file and select Properties.
- Under the General tab, untick the Read Only option.
On a Mac Computer:
- Right-click the file and select Get Info.
- Select Sharing & Permissions.
- Edit the permissions.
Fix 3. Disable Protected View
Ensure that you disable protected mode before attempting to sign the form. Here’s how.
- On the Adobe Preferences menu, move to the Security (Enhanced) tab.
- Untick the Enable Protected Mode at startup.
- Restart the system before the changes can take effect.
Fix 4. Change Adobe Signature Preferences
Resolve the incompatibility of the signing feature using the steps below.
- Launch Adobe Acrobat and go to Preferences > Signatures.
- Click More next to Creation and Appearance.
- Check the Use Modern Interface for Signing and Digital ID Configuration box.
Fix 5. Change Warning Preferences
Warning preferences can prevent the document from being signed. Signing could be blocked by the software until you review all warnings. Here’s how to adjust warning preferences.
- Open the Preferences menu and browse to the Signatures section.
- Access the Enable Review of Documents Warning option and set it to Always.
- Locate Prevent Signing Until Warnings Are Reviewed and set it to Never.
- Save your changes and attempt to sign the document again.
Fix 6. Check for PDF Certificate Issues
When PDF security features block signing, examine the document’s security settings using your PDF editor. If a security certificate restricts signing, you won’t be able to bypass it. Requesting an unlocked document from the author is the ideal solution, as only they can change the restrictions to enable signing.
Fix 7. Update the Outdated App
An outdated Adobe app can create issues with e-signatures. In such a case, it is advisable to update the Adobe application’s OS to the newest version available on the official website.
