Upgrading to latest Version OJS 3.1.2.1-1 and Encounter the Http error 500

[Darryl_Nuyda]

Hi Everyone;

Good day to all;

App Version: OJS 3.1.1 want to upgrade OJS 3.1.2-1;

The Issue of Upgrading to the latest version due the encounter problem of “Page is not working” and “HTTP Error 500”. I put in my mind that need to upgrade our OJS to the latest version. Almost 2 years that I last upgrade the of our OJS.

Our Server is a Go Daddy VPS recently the go daddy suggested to upgrade in the new apache version, but I doubled check the OJS after upgrade no changes at all and no problem encounter. Lately, when our editor submitted the papers to upload in our ojs website, I m very shock when the site is not working with the error “HTTP Error 500”. Screenshot see.

Upgrading the new version using the Shell Xampp and follow this process “php tools\upgrade.php upgrade” but the error. Please check the screenshpt.

Before, I came here this forum I downloaded the new version and Sql file to the server and transfer the localhost using XAMPP Platform. I follow the instruction how to conduct the processing, backing Up for the seek of not successfull upgrade. But, the error is not solve. I go to first the https://stackoverflow.com for the help and search the solution, watching videos follow the instruction but saddenly the is still here even in my localhost.

I am trying to resolve the HTTP Error 500 and the Upgrade the new Version.

The Error log Message from Server Cpanel:

See:

HTTP ERROR 500 message on web browser

Hi @purple, Try switching your database connector in your config.inc.php from “mysql” to “mysqli”. Cheers, Jason

[Darryl_Nuyda]

Hi @ctgraham;

Thanks for the reply.

Done for Upgrading the to the new version But, I got this error.

Please see attached file;

thanks

[ctgraham]

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!

[Darryl_Nuyda]

@ctgraham thanks for your help.

[Darryl_Nuyda]

@ctgraham;

hi,

I got this error when I visited the journal page site.

Thankjs

[Darryl_Nuyda]

@ctgraham;

When I tried to create the new Issue, Still Loading …

Please help;

[ctgraham]

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.

[Darryl_Nuyda]

@ctgraham,

Here is the error:

When, I go to the administrator Journal Page for Submission

2nd Error:

Creating Issue for New Volume.

3rd Error:

Here is when I go to Back Issue.

Thanks

[mpbraendle]

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

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

[Darryl_Nuyda]

@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

[mpbraendle]

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.

[Darryl_Nuyda]

@mpbraendle;

Here Screenshot;

Thanks

[mpbraendle]

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

[Darryl_Nuyda]

@mpbraendle;

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

Sorry wasting your time for this inquiry Sir.

[ctgraham]

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?
