Will you kindly let me know how to find web server error log?

[israel.cefrin]

Sure.
A typical location for all log files is /var/log and subdirectories.
Try /var/log/apache/error.log or /var/log/apache2/error.log.
If the logs aren’t there, try running
$ locate error.log.

[Vitaliy]

Is this a standard PKP plugin?

[sciplatform]

You may find a how to find PHP error’s log in this thread:

How do I find my PHP error log?

Where you’ll find your PHP error log will depend on your server’s setup. In most shared hosts, there is a directory called logs or something similar. If your service provider has a knowledge base, they will typically describe how to find your logs there. If you’re running your own server, logs will usually be somewhere like /var/log or /var/log/apache. There are many useful threads in StackOverflow that may help to find your logs. For example: http://stackoverflow.com/questions/5127838/where-d…

A question, haven’t you change your sidebar directly in DB, have you?

I am not sure that I have change the sidebar in my data base. I can check and I will let you know if you guide me.

[israel.cefrin]

Have you run a SQL statement or edit any table in your database with PHPMyadmin or by terminal? In ay case,I recommend to restore a previous backup to put your site back on track and verify what your update attempt may have broke in a local test version before you try update again.

Thank you for your valuable suggestion but I have restore the backup of 20-sept-2017 but the issue is same. If any thing else please advised.

[asmecher]

Hi @sciplatform,

I suspect you’ve altered your sidebar block configuration to put the keyword block plugin onto the site-wide homepage. It’s not written to work this way – it expects to live within a journal’s context. If your site continued to operate despite this change being made, it’s possible that your cache directory contained outdated cache files that were taking effect rather than the database changes; flushing the cache files might cause this to suddenly appear, as the cache would be re-generated from the database table. I would suggest reviewing any changes you’ve made to your plugin_settings table for the keyword block plugin. Unfortunately we can’t walk you through this in detail.

From Asmecher suggestions, I have tried the following possible solutions.
I have tried delete the old files and upload the new one. The issue was same
I have tried to make the changes in the but all in vain.
I have removed the plugin and website is working fine.

Thank you israel and Asmecher
