[OJS 3] Plugins Tab doesn't load

Hello and thanks for the support.

The plugins tab on Website Setting doesn’t load anything, and if I click directly on “Installed Plugins” nothing happens:

There was no problem on 3.0.0 version, but after upgrading to 3.0.1

Hi @Ayax,

Can you check your PHP error log and browser Javascript console to see if something relevant appears there?

However, the .png listed are in their correct directories…

Hi @Ayax,

Have you checked your PHP error log?

Hi @asmecher ,
PHP error log is empty. Same result with various web browsers (Safari, Chrome, Firefox).

Any way to change plugins status with plain config file?

The message of “500 (Internal Server Error)” will almost certainly result in a PHP error begin recorded. There may be different error logs for Apache vs. for PHP, and there may be multiple log locations depending on the host.

Check with your system administrator or hosting support regarding where the PHP errors are logged in your server.

New issues after upgrade to OJS 3.0.2
And plugins gallery still unload.

Hi @Ayax,

Try viewing the plugin gallery, then checking the error log immediately to see if there are messages with corresponding timestamps. This will help determine which, if any, of the messages above are relevant.

Try searching this forum for messages related to the unserialize function. There are already several threads about this and how to resolve it.

I am also facing same problem…and as I am new with PHP do not know much about php.ini

can you tell me how to fix it up. It would be great help.

my site is ijsu.org

Hi @naveen_kumar,

Can you describe your situation more exactly? What version of OJS are you using, what are you trying to do, and what is the result? Have you checked your PHP error log for details?

HI,
I am using ojs 3.0.2 . I have read similar threats, where it was suggested that to configure tar tool but i do not know how to configure the tar tool in your config.inc.php file,

second thing I also tried to see the log files , but I could not get any related log showing error.

I am also having problem when I try to upload any image file for logo or for cover.

As I am new to this system, I need little more help. Can you please tell.

regards

Hi @naveen_kumar,

You’ll need to start by locating your PHP error log. The specifics of this will depend on your server configuration, so if you’re not sure where to find it, you’ll need to ask your server administrator/service provider.

Hello Alec,
I have the same problem like Ayax my OJS is 3.0.2).
I changed and deleted some themes and after that, I can’t load Installed plugins page. My php error is:
"PHP Fatal error: Cannot redeclare class DefaultManuscriptChildThemePlugin in /home/ojs/public_html/plugins/themes/defaultManuscript-master/DefaultManuscriptChildThemePlugin.inc.php on line 0, referer: http://ojs.kbf.unist.hr/index.php/proceedings/management/settings/website"
Any advice?
With Bets Regards

Hi @zmatas,

It looks like you’ve installed two copies of the “default manuscript child theme plugin” – remove one of the two.

Hi Alec,
well, I first installed defaultManuscript Theme, but it didn’t work. Then I installed defaultManuscriptMaster and the theme worked. But when I installed some other themes, ojs simply couldn’t load the installed plugins tab. Now I removed master and loads normaly.
Thanks for your time and help.
With Best Regards
Zeljko

Is it possible that no one knows the reason for this? I have the same issue, installed plugins loading fro the past hour, but nothing showing. I installed OJS 3 last night, first installation, I didn’t mess with anything, and the plugins don’t load.

PS. Console says this: Failed to load resource: the server responded with a status of 500 (Internal Server Error)

Hi @filipi

Try to click on the error that is showing in console and verify which resource give you error 500, perhaps it helps to isolate the problem.

Hi @israel.cefrin, I’m afraid I have no idea what to do. I am not a developer. Shouldn’t this be a user friendly software? I don’t have a PhD in computer science. I tried everything and I do not know how to fix it. The error seems to point to Google Scholar Indexing Plugin.

PS. Now that I tried again, it points to another plugin HTML Article Galleys:
