OJS 3.2: Plugins not loading

Software Support
1

Hi,

My “installed plugins” are not loading, here’s a screenshot of my issue:

This is the only error that my php log provides when I try to load the plugins section on the global administration:

[Tue Jul 28 07:13:22.645228 2020] [autoindex:error] [pid 2763:tid 140148230563584] [client 172.16.29.2:55955] AH01276: Cannot serve directory /ojs/ojsProd/public/site/: No matching DirectoryIndex (index.html,index.php) found, and server-generated directory index forbidden by Options directive, referer: https://XXXXXXX/index.php/index/admin/settings

but when I’m on a Journal, the log doesn’t throw any error however the navigator console throws the following:

I tried by replacing the plugins folder with the default one that is on the github: GitHub - pkp/ojs: Open Journal Systems but it doesn’t work.

Could this be a problem with the firewall of the company or something like that?

Best,

Juan

Hi @Juan_Lopez,

There should definitely be a server-side PHP error to go with that 500. Make sure you’re checking your PHP error log, which might be kept separately from your web server (Apache) error log.

I don’t recommend replacing the plugins directory with something from github unless you know which branch you need to use – it’s probably incompatible.

This is my php.ini configuration for the error log:

display_errors => Off => Off
display_startup_errors => Off => Off
error_append_string => no value => no value
error_log => /var/log/php_errors.log => /var/log/php_errors.log
error_prepend_string => no value => no value
error_reporting => 22527 => 22527
html_errors => Off => Off
ignore_repeated_errors => Off => Off
log_errors => On => On
log_errors_max_len => 1024 => 1024
track_errors => Off => Off
xmlrpc_error_number => 0 => 0
xmlrpc_errors => Off => Off
opcache.error_log => no value => no value

is there something that I’m missing in this configuration and thats why my php_errors.log is not showing any error?

Hi @Juan_Lopez,

This is more of a PHP question than an OJS question – maybe look through StackOverflow, e.g. log files - error in php not logging or displaying - Server Fault?
