keywords_all() no longer returns any data?

Not sure when the problem started but guessing over the last couple of weeks keywords_all() has started to return no data.

The normal keywords() does still work but it is missing many of the keywords.

From what I can tell from looking at the cached keywords page file the keywords are still in the retrieved page but perhaps the formatting has changed and that is causing the problem.

Thanks

Thanks for this - I manually applied your code changes and it is working great 👍
