XF 2.2 Internal Server Error when trying to edit

[drerr]

I am inconsistently getting an error when trying to edit posts.

Error log on the server has:
[05-Oct-2023 19:50:22 UTC] PHP Warning: require(###########community/src/vendor/composer/../laminas/laminas-zendframework-bridge/src/autoload.php): Failed to open stream: No such file or directory in ###########community/src/vendor/composer/autoload_real.php on line 53
[05-Oct-2023 19:50:22 UTC] PHP Fatal error: Uncaught Error: Failed opening required '###########community/src/vendor/composer/../laminas/laminas-zendframework-bridge/src/autoload.php' (include_path='.:/opt/cpanel/ea-php81/root/usr/share/pear') in ###########community/src/vendor/composer/autoload_real.php:53

I see the files that are referenced, so it is not clear what is missing or misconfigured. Can someone help with this?

Do the files exist on the server?

If not, upload them.

If they do, server permissions may be involved.

I see the files. Sometimes editing is allowed, sometimes I get an generic, unhelpful message from the XF installation and error log shows the above.

What server permissions might be the problem?

 

[Paul B]

If the file can't be served then it will be due to permissions or ownership.

If the errors are random, you likely want to get your sysadmin or host to investigate.

What are the file permissions supposed to be?

I am attempting to investigate, but XF is not mine and I don't know the assumptions.
