Slim application error

Software Support

  • Application Version OJS 3.3.0-6

My problem is that when we uploading files during the submission process, we got “slim application error”. We used this setting for localization setting:

;;;;;;;;;;;;;;;;;;;;;;;;;
; Localization Settings ;
;;;;;;;;;;;;;;;;;;;;;;;;;
Capture

[i18n]

; Default locale
locale = en_US

; Client output/input character set
client_charset = utf-8

; Database connection character set
connection_charset = utf8

database_charset = utf8

charset_normalization = Off

would you please help us to solve this problem?

Hi @rashad,

Are you able to provide any relevant output from your PHP error logs? If you could provide that here that would be appreciated and could help to identify the issue. You may also wish to see this post here, where a user identified a similar error: Slim Application Error when uploading article - #8 by rebas_saber

Best regards,

Hi @rashad,

Thank you for supplying this log information. I’m not sure what to suggest here, but other members of our team and community members may wish to give their suggestions.

hi @rcgillis
Okay, I’m looking forward to hearing from them soon.

Hi @rashad,

It looks like this is the relevant line from the error logs.

It looks like the function _setupIssueTemplate() is getting passed a boolean instead of an issue, so $issue->getIssueIdentification() on line 288 of /home/kararyedu/public_html/Journals/pages/issue/IssueHandler.inc.php is failing.

Have you run an upgrade recently? And if so, did this problem only start after the upgrade was complete? You could check and see if there’s anything strange going on with the issues in the database that might be leading to this problem.

Was this issue resolved? I am facing the same issue. and I am using PHP 7.4 and fileinfo module is also installed.

Hi @deepak.kikan,

Could you share any error logs you have as well as which version of OJS you are using? Thanks.

Thanks @ewhanson. I am using OJS 3.3.0 and PHP 7.4 and though fileinfo was installed on the server, it wasn’t enabled for PHP 7.4 in multiPHP environment. So, the issue got resolved now. By the way the error was Type: Error
Message: Class ‘finfo’ not found
File: /home/zitco/public_html/interjournals.org/ojs/lib/pkp/lib/vendor/league/flysystem/src/Adapter/Local.php

I also found something important in case someone doesn’t have control on the server to install fileinfo extension or other issue. Flysystem, the one that used for mime type detection also provides implementation that is not dependent upon fileinfo. Please check Mime-type Detection - Flysystem (thephpleague.com). I tried couple of solutions from this page but couldn’t get it working. Maybe, someone from core team take a look at it and try.
Thanks again.
