We have removed some bugs in our WordPress PDF Plugin service on pdf24.org. There was a bug in email texts of sent emails with the PDF file attached. It could be that the text was formatted wrongly. YXou can configure the email text in wordpress admin property pages. There are a lot of options which can be changed to costomize the PDF24 WordPress PDF plugin.
Forthermore we have removed a bug in pdf filename building methods. If there are HTML special characters which should become part of pdf name this special characters were not been converted back to the right character. The special HTML character code has become part of the pdf filename which leads to a bad filename.
All changes have been made onb pdf24.org server so you don't have to update your wordpress PDF plugin.
