Curl_multi_exec() has been disabled for security reasons

Hi

I installed Grav for the first time (from the zip file of a skeleton) on my usual hosting, and I was very pleased to see that all the checks were successful ("PHP Modules: All modules look good!", "Essential Folders: All folders look good!", ...).

Unfortunately, for every page I visit in the admin interface, I see the following message (in a red popup):

curl_multi_exec() has been disabled for security reasons

I checked the my PHP setting and actually my hosting disabled this PHP module (it is in the "disable_functions" section).
Therefore, I asked them to enable it but they told me that they cannot do this due to some security vulnerability since this is a "shared hosting".

However, I do not see this as a strict requirement for Grav in the documentation.
Can you tell me if it can work also without this module?

Is there a way to fix this problem? (perhaps some settings that I can change?)

Thanks

@DaniloP, A bit of research tells me that curl_multi_exec() is being referenced by vendor library CodeMirror, which is a Javascript based text editor and probably used for Markdown. Only Admin makes use of it.

It seems you have a few options:

• Choose a different hoster.
  I haven't seen anyone bumping into this issue in over 3 years...
• Don't use Admin
• You may test your luck and see if there is a plugin that allow you to use a different editor like e.g. TinyMCE.

@pamtbaau Thank you for your quick answer.

Unfortunately, the site will be managed by "not-expert" people, and they will really need a "nice" user-interface.

I tried with different editors but the problem is still there and it is still causing problems.
These are some of the problems that I believe are due to this missing module (because locally they seem to work properly):

• in the Dashboard page, the Notifications component keeps loading something forever (there is always the "spinning wheel")
• in the Dashboard page, the "News Feed" component contains a "warning sign" and the following text curl_multi_exec() has been disabled for security reasons
• when I click the Add button in the Plugins page, it loads the "Available Plugins" page but I do not see any plugin and I get the message The connection to the GPM cannot be established
• In the Site tab of the Configuration page, if I try to save (even without modifying anything), I get a "Forbidden" error (403). This does not happen in the other tabs (for instance, in System)
• ... (let me know if you want more, but I think these are enough to support my following question)

Do you know if this PHP module is used somewhere else?

Thanks

@pamtbaau thank you for checking this.

It seems that I need to change my hosting provider...

Probably this should be added to the "requirements".

Thank you very much for your help.
