Code:

[Wed Nov 10 20:54:31.472312 2021] [php7:error] [pid 5776] [client 206.125.202.234:58067] PHP Fatal error: Cannot redeclare GuzzleHttp\\json_decode() (previously declared in /var/www/html/[redacted]/html/libraries/CBLib/GuzzleHttp/functions.php:299) in /var/www/html/[redacted]/html/libraries/cjlib/vendor/guzzlehttp/guzzle/src/functions.php on line 147, referer: https://[redacted]/en/component/comprofiler/registers

Yes, that is an incompatibility of the third-party library "cjlib", which seems to include (force-load) (instead of auto-load, which would not load it if already defined) their GuzzleHttp. You should imho report that to the author of the "cjlib" library so that they don't include their libraries, but auto-load them, which will not load them if already defined. Now that might most probably help, but I can't exclude issues if the versions differ a lot. On our side, once we release CB 2.7 which increases minimum php version from 5.6 to 7.4, we will be able to upgrade the Guzzle library to very latest one.

cjlib developer replied:

Unfortunately, that is the wrong interpretation. CjLib does not force load the library. It uses composer autoloader to autoload the libraries. Whereas CB uses a very old version of Guzzle (v4 I believe) and CjLib uses the latest (version 7 which is also PSR7 compatible). I believe this is the reason for the composer could not detect the already loaded version. If CB can support the latest library, I believe it is the best solution.

=========================

Incidentally, I notice one guzzle is lowercase and the other is camel-case... strange that its not case-sensitive??

Anyway, i'm not sure what to do (if i can roll back to earlier cjlib or not).
Is CB2.7 coming out any time real soon?

Nothing we can do about this right now. The two versions are incompatible. I'm not sure what cjlib is for, but why is it loading during user save? and why does it need Guzzle during user save? CB should only load Guzzle around that time if using reCaptcha captcha in CB AntiSpam, during various CBSubs payment gateway communications, if using link feature in a video or audio field type, if using a Request action in CB Auto Actions, or registering via CB Connect.

Is CB2.7 coming out any time real soon?

We do not have a time frame for when CB 2.7 will be available. Ideally in a few weeks as we want to bump our minimum PHP to 7.4 finally.
