I have ojs version 3.4.0.4 installed, it was working perfectly well but I don’t know what happened to its installation as it is there in Cpanel but nothing is shown in brower. I don’t know what to do because in cpanel it seems fine but in browser it is just vanished. Following is the error.log

Hi @Azhar_Munir

The error_log information you provided indicates that the hosting you are using has disabled the proc_open feature. Therefore, you can contact the hosting provider to enable this feature.

Regards
Almadani

Thank you sir @Muhammad_Al_Madani but I have checked from my hosting provider and they say proc_open feature is already enabled. Now the situation is that the software is working by using the backup but no email is sent to reviewers and to the new rigisterants of the journal. The new error log is here.
I am using (ojs version 3.4.0.4

@rcgillis @asmecher anyone, please help

Hi @Muhammad_Al_Madani,

The problem is as @Azhar_Munir described above – the proc_open function is disabled in your PHP configuration. If it’s been removed from the configuration, it might be necessary to restart the server.

Regards,
Alec Smecher

Thank you @asmecher for your help and support
Let me look into it.

Hi @asmecher
I am sorry to bother you again and again. Last day when I was checking different views of preinstalled themes. I selected bootstrapping theme with the option of journal and when I applied to view the changes the journal become inaccessible again. I reselected the previous theme and saved but it is showing http error 500 but its dashboard is working only website is not showing up. I am using ojs 3.4.0.4 version. Its login page is intact but after clicking on login there is no home page shown.
