thanks

The “PHP Notice” is a development-oriented message, and can be suppressed/ignored in your production environment. You would be interested in any messages of “PHP Error” in the output.

The message “Successfully upgraded to version 3.1.2.1” means that you have completed the upgrade without any critical blockers. Congratulations!

Please help;

For these errors, please check your PHP error log for any relevant messages with a prefix of “PHP Error” or “PHP Fatal”. Also check your Web Inspector console for any javascript error messages. Paste those messages here so we can see what is going on.

@ctgraham,

Here is the error:
Error_OJS
When, I go to the administrator Journal Page for Submission

2nd Error:
Error_Creating%20Issue
Creating Issue for New Volume.

3rd Error:
Error_Back%20Issue
Here is when I go to Back Issue.

Thanks

The PHP error log will be the most important place to look at. Please do so as @ctgraham has described above.

@ctgraham;

I checked the Web Inspector console here is the message error,

These messages are all pointing to a PHP error, which should be recorded in your PHP error log.

@ctgraham

I tried to delete the error_log and still remain looking like this problem.

can yuo help me how to fix on this?

Thanks

Please read what ctgraham and I have written before. The PHP error log is (in most cases) the important place where to find the reason.
You can find the PHP error log as follows.
Log in to OJS back end as admin.
Click “Administration”.
Click “System Information”.
Scroll down the page to the end.
Click “Extended PHP Information”
Find “error_log” in the “Core” section. It indicates the path of the PHP error log.
Please then post here an excerpt of the errors you find there when you call a page in OJS.

Here Screenshot;
OJS_Error_1 OJS_Error_2 OJS_Error_3 OJS_Error_4

Thanks

This does not help. Do as advised. Please don’t post unnecessary screenshots.

@mpbraendle;

Okay. This not help for. I will try to check and Understand.

Sorry wasting your time for this inquiry Sir.

You will need to find the PHP error log and look in this file to find the details on the actual error. In the screenshots you provide, the PHP error log is named “error_log”, but additional location details are not shown. Check with your system administrator or hosting provider if you need assistance finding this file.

Once you know where the PHP error log is located, generate the error again so that a new message is at the end of the log, then open the error log file. Copy and paste the message or messages which correspond to the time of the last error.

Hi all,

Have a look at this: How do I find my PHP error log?
