It's the unix timestamp of your server.

Please check your error log to find this timestamp and learn more about error.

Thanks for the quick response. This site is on JustHost and I am in the phpMyAdmin and see the errors. How involved will this fix be? Does a message like this mean someone was hacking the site?

"Access denied for user 'root'@'localhost' (using password: NO)"

Does a message like this mean someone was hacking the site?

You need check syslog​ on your server to find out what happened.

Can you change the MySQL password?

If yes, do it.

Which your Elgg version?

It is Elgg 1.8.8 I downloaded the error log and seems like unusual activity started Nov 12 with this error message:

[12-Nov-2020 19:39:41 UTC] PHP Warning:  Version warning: Imagick was compiled against Image Magick version 1654 but version 1650 is loaded. Imagick will run but may behave surprisingly in Unknown on line 0

Password changed just to be safe.

Version warning: Imagick was compiled against Image Magick version 1654 but version 1650 is loaded. Imagick will run but may behave surprisingly in Unknown on line 0

Seems, your hoster has updated PHP version to 7.3.

I would suggest reinstalling the imagick pecl module.

If you're on the shared hosting then contact your host support.

Elgg 1.8.8

It's sad. 

If I'm right and you have PHP version 7.x and above, I'm afraid you need to either downgrade to PHP 5.x or update your Elgg.

Can you check your PHP version right now?

Password changed just to be safe.

Don't forget edit your Elgg settings also:

PATH_TO_YOUR_ROOT_INSTALLED_ELGG\engine\settings.php

section:

$CONFIG->dbpass = 'YOUR-NEW-PASS-HERE';

Do you have this error in your log ?

Error: Call to undefined function mysql_connect()

If yes, you're on PHP 7.

I have that error and am glad to see that it is not likely a hacking issue. I am guessing that upgrading may have some unintended consequences since I did a lot of formatting for the Elgg site but would the content be available? This is quite a few version jumps up. Are there any threads on that process or should I look into downgrading my PHP instead?

This page probably has the most custom elements.

Sure, the process is very hard but sooner or later everyone goes through it. 

If you have many custom plugins, or plugins that haven't yet been updated, the update may take months.

At the same time, you must code or have someone who knows how to do it.

It was a challenge for us too but we did it.

Are there any threads on that process

Try search.

Me and iionly wrote a lot about it.

In addition, I can also give these snippets for you:

Thank you very much. Jazfry isn't an active community, so I will take my time with it and see if 3.x is a good fit for some of the active spaces that I am working in.
