Incompatible PHP version
If your installation shows signs of PHP version incompatibility, such as
- “CSPRNG fucntinons not available” exception
- various fatal Parse errors in Mpdf codebase
make sure both your PHP version in console and in the server environment is supported. Checking
does not suffice, try inserting
var_dump(PHP_VERSION); die; right before your mPDF code to find actual PHP version
used with mPDF.
