I'm quite new in dokuwiki, so please excuse my lack of knowledge.
I have a problem with the dokuwiki setup.
I tried copying old dokuwiki instance and moving it to a newer installation.
i made a clean install:
php 7.2 ( and 5.6 tested too) with all necessary libs (cli,common,gd,mbstring,mysqlnd,xml and many many more)
Release 2018-04-22b "Greebo" dokuwiki
Latest version of dw2pdf (january 2020)
latest version of plantuml and graphviz
libs for graphviz installed locally
java for plantuml installed locally.
Pages are displayed correctly, but when exporting a page containing a dynamically generated picture (like plantuml or graphviz), the image is changed to a little red 'X'.
The 'X' leads to a proper URL (like https://path-to-wiki.com/path_to_plantuml/img.php?width=0&height=0&title=PlantUML
Graph&align=&version=2011-07-16&md5=041ec428a76be1d503f8eb8b6d4ecxxx) that, when clicked, displays the image, but in my opinion it should've been rendered into the pdf.
Non-dynamically generated pictures are rendered into a pdf without a problem.
I tried many things, even changing img URL's in plantuml to include a pseudo protocol dw2pdf:// but that didn't help.
What might be wrong, guys?
I'm running out of ideas. Please help.
