PDF File Security Settings
Field “Allow copy” is unchecked – but copying text from the stamped file is still possible – even after “Reset to Default” and testing again.
PDF Stamper v4.1.9 – eStore v188.8.131.52 – WordPress 3.5

You have the “Enable PDF File Encryption” field checked in the PDF File Security Settings correct? You need to enable that to use any of the security settings options to take effect.February 13, 2013 at 2:12 pm #53146
Thank you for responding so quickly.
Yes, I had enabled “PDF File Encryption” before stamping. But then I got a blank page, no error, no stamped file. Following your checklist I also tried “Stamping Method 2”, also stamped with your example, but no success.
With the option “PDF File Encryption” UNchecked stamping of all the different files went fine.
I needed some time to figure it out, but finally I was able to solve the problem as follows:
- Removed W3 Total Cache and made my own .htaccess.
- Made a new PDF file using a better PDF maker (“Nuance PDF Creator”) – with the option “Embed Metadata” UNchecked.
As a result encryption was working, manual stamping went well and my test order with my eBook – correctly stamped – was ok as well.
At last I could open my eStore [http://www.natuerlich-schwanger-werden.de]
Thanks again and kind regardsJune 12, 2013 at 9:52 pm #53147
I don’t understand what D. devries did to solve the problem, but I have the same.
Files for which I’ve removed the right to copy give me an error when stamped:
File is encrypted! Error Code: 6
What do I need to do to ensure that my PDFs are not able to be copied (or saved) AND still are able to be stamped?
ThanksJune 12, 2013 at 11:34 pm #53148
I made a completely new PDF file – WITHOUT ANY security or other options (see also ‘Error-Checklist 2 and 3 on:
Your uploaded file seems to be encrypted and not writable by the stamper.
Success!June 13, 2013 at 12:34 am #53149
@D.devries, Thank you for your answer.
@sitkapacific, Please make sure the source PDF file does not have any encryption or protection (as suggested by D.devries). You can tell the stamper plugin to apply protection to the stamped copy of the file (your customers will receive this stamped copy of the file).June 13, 2013 at 5:33 pm #53150
I have removed the encrypted pdfs and uploaded ones that are not encrypted. I went to the settings and checked the “Enable PDF File Encryption” and the “Allow Print” boxes. When I try to go to view a document online – most of the time I get the error “An error occured while trying to stamp the file! Error details: ” If I try it several times sometimes the document does load without the error. If I un-check the encrypted checkboxes the documents load everytime. If I check them again then I have the error problem again sometimes-randomly. What can I do – thanks for your help !June 13, 2013 at 11:58 pm #53151
Encrypting a PDF file is a resource intensive process, so it won’t work smoothly if the server can’t handle it. What sort of hosting package are you suing? What is your PHP memory limit on this hosting? How large is your PDF file (the one that you are stamping and encrypting)?June 17, 2013 at 7:24 pm #53152
Default is 128 MB but I can change it. We are hosting at Rackspace Cloud Sites. What should I set it to to avoid any problems? PDFs can be as long as 20 pages with graphics- call it ~1.5 MBJune 18, 2013 at 3:04 am #53153
Try upping the memory to 256 MB.
