Sorry for not filling the form previously...

Can you also make a report to https://github.com/ezyang/htmlpurifier? Because that doesn't seem like an issue in news.

[FadeFx]

Did so: ezyang/htmlpurifier#428

@SMillerDev is HTML Purifyer included with news somehow, or is it installed in the os? I am asked to try and reistall it, but I did not install this in the first place. This could however also be due to it being included in nextcloudpi...

[Grotax]

It is shipped with news as a dependency hence the path that includes news.

But I have no idea why you see that in your logs.

[SMillerDev]

It's part of the news app. Maybe the v25 release of today will help?

[Grotax]

@SMillerDev just checked my logs I also see these warnings and I'm running 25.0.0

[FadeFx]

Updated to 25.0.0 and it keeps logging

ezyang/htmlpurifier#428 (comment)

[FadeFx]

Actually it is very likely something you imported with the Alpha14, as the issue was not there before.

It was updated in alpha13 (791ea20) from v4.17.0 to 4.18.0 which added this as new feature:

add directive for removing blank nodes (ezyang/htmlpurifier#404) (c9d60c9)

Probably, I think I jumped alpha 13

[pbek]

Should we revert 791ea20 meanwhile?

[FadeFx]

I think this can be closed, as the downgrade removed the issue, however, it should be keept in sight for next upgrade attempt...
