Hello,

The following frequent issues seem to apply to your support request: (This is a semi-automated response):

  • Missing URL to reproduce the problem.
  • Does this appear on all pages, including the home page and including the back-office?
  • It would be nice if you would put the version in the correct fields when submitting a bug report.

I have a log file that is about 1GB per day at the root of the website that contains this error and it uses 80% of the CPU. If the websites are closed, there are no more errors in the logs.

There is no message in the interface of the b2 website, so it will not be possible for me to provide screenshots that I don't know where to look.

I had this same error using the Facebook widget. This fix solved the problem. I posted my report in the wrong location and later found this solution.

Thanks

Hi Looking at this

mb_strrpos(
    string $haystack,
    string $needle,
    int $offset = 0,
    string|null $encoding = null
)

https://www.php.net/mb-strrpos

/inc/_ext/_url_rel2abs.php on line 157

Try editing line 157 from
(mb_strlen($path)-1) == mb_strrpos( $path, '/', 'UTF-8' ) )

to
(mb_strlen($path)-1) == mb_strrpos( $path, '/', $offset = 0, 'UTF-8' ) )

I've made the changes to one of my 7.2.3 collections with no down side, yet :) but I don't use Facebook so can't test.

Thanks for the prompt, I'm not looking at code for quite a long time, though I think this issue is not the same as the topic ??
