after clearing cache I get ERR_EMPTY_RESPONSE

[netamismb]

Hi all,

Is happening for me on local environment Windows 10 WSL debian 9, PHP 7.3 Apache2  quite often, Thirty bees v 1.1 after I cleared cached i get ERR_EMPTY_RESPONSE and a page blank without any clue.  Any idea what could cause this and how can prevented?

There are no logs in error_log, just a warning and notices, which were there all the time.

Any advice is highly appreciate.

Do you need module "cheque"? If not, uninstall and delete it.

Uninstalling and deleting unused modules is generally a good idea. This brings a small, but existing performance advantage over just disabling it.

[Occam]

First of all this doesn't seem to be the current release of the cheque module because there is no count() argument  in line 66. However, if you meet this error or warning in PHP 7.3, then do this:

• Open the file, in this case cheque.php,
• go to the the questioned line and
• change the expression count to is_countable.

This will help to avoid the message.

That said, let's go to the ERR_EMPTY_RESPONSE, an error known from the Chrome browser. Try this: https://blog.pcrisk.com/windows/12807-err-empty-response

Anyway, your initial error message had nothing to do with this module. The advice of Traumflug referred to the PHP 7.3 notice on using count() in error.logs.

The err_empty_response i suspect is related with WSL but still not sure yet. Is happen for time to time, and sometimes is fixed reloading apache2.
