Edit htaccess

You have to add this line of code code in the .htaccess of your WordPress root directory.

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]


RewriteEngine On

There are several ways to edit this file. Here is a short tutorial thats explaining how you can edit it if you do not know.

The full htaccess looks now like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress

Update Fonts

In new version you can finally use TrueType fonts (ttf). This font format is also required if you want to embedded the font in the exported PDF. Please replace all .woff font files with TrueType fonts in the fonts folder (wp-content/uploads/fpd_fonts), if you have used custom fonts.
After that go to Settings/Fonts tab and save all fonts.

Please note that the font embedding in PDF is only working with orders that you made with the version 3.4.
