For a while now, I am getting "Sorry, something went wrong. One or more resource files failed to load. Please try your query again." on any Technical Support / Knowledgebase Search I do on https://www.ptc.com/en/support/.
What can I do?
This is still an issue. No search is possible with Firefox 63.0.3.
It seems to work with Chrome.
The issue persists and now search does not work in Chrome any more.
Any help is appreciated.
Support changed my permissions so chrome works again.
Firefox works after disabling the "ublock origin" extension for the PTC site.
Maybe it might be of interest for someone else.
