Would it be possible if you possibly ‘Allow\_url\_fopen is not enabled!’ would go, otherwise everything works out for me, only that does not work for me ☹😢 .
Thank you \<3

This is the php code with which Perfex CRM checks if it is enabled
```
$ url_f_open = ini_get ('allow_url_fopen');
if ($ url_f_open! = "1" && $ url_f_open! = 'On') {
$ error = true;
$ requirement11 = " Allow_url_fopen is not enabled! ";
} else {
$ requirement11 = " Enabled ";
}
```
it is the right way or not - I have no idea

I’m not in possession of that
but I download this [https://www.perfexcrm.com/perfexcrm-requirements.zip](https://www.perfexcrm.com/perfexcrm-requirements.zip)
and probably the same thing is used during the installation

That’s great, thank you, let me know if it worked for you or you could possibly find a solution, would be really nice

I tried it right after your first post
it does not work (unable to recognize)
Try to go [Login - Perfex CRM](https://help.perfexcrm.com/forums/)
and open a ticket because they might have some workaround

I did some checking, and if this really is the code Perfex uses to check if `allow_url_fopen` is enabled, then Perfex clearly messed up here. That code to check whether the setting is enabled is plainly wrong.
The script checks is the setting `allow_url_fopen` is set to `1` or `On`, which are both valid ways to enable an option in PHP. However, in our server, the setting is set to `on` (fully lower case). The script checks whether the setting is equal to `On` rather than `on`, so it incorrectly believes that the setting is not on.
Options in PHP which can be turned of can be turned on with `1`, `on`, `true` and `yes`, (and any capitalization) and turned off with `0`, `off`, `false` and `no` (again, all capitalization are valid). Additionally, an empty setting should be considered equal to `off` and any other string or number should be considered `on`.
This is how PHP itself parses it’s config file:
> String values “true”, “on” and “yes” are converted to TRUE. “false”, “off”, “no” and “none” are considered FALSE. “null” is converted to NULL in typed mode. Also, all numeric strings are converted to integer type if it is possible.
Send this to Perfex with the message that they should fix their code.

@BatMen
try this address
perfex\_crm/install/requirements.php
and then search the code (url\_f\_open)
and edit so that `On` becomes `on`
then save and try installing and let us know if everything is ok
