Admin Keepalive Timer [Support Thread]

[DH010010]

Is there any way to adapt this to work for the main site? I am looking to display the same idle warning to logged in customers. I have tried and failed..... any help would be great :o)

Running zc 1.5.3

[lat9]

Guys, I'm having a blank page after the time-out on the admin panel, the log file is pointing to this line in the admin/keepalive.php on line 12
Which is: header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
and the whole log's info is:

PHP Warning: Cannot modify header information - headers already sent by (output started at /home1/public_html/newadmin/includes/keepalive_module.php:34) in /home1/public_html/newadmin/keepalive.php on line 12


Is that happening because I changed the time format from the US ( M,D,Y) to GB ( D,M,Y)? and how to fix the problem with the blank page ?

Can't seem to replicate this on my own site.

What's different in your admin files compared to a fresh brand new uncustomized install of ZC?

The issue is with the November 2013 (v1.0) update, where an initialization script was added to load the keepalive_module.php. Since that module outputs a <div>, that's where the error originates. Using the previous (beta0.3) version corrects the issue (albeit with a single-line modification to the admin's /includes/header.php).

Just remember, don't use this plugin for Zen Cart v1.5.2 and later ... it's already included!

I installed 1.5.3 from scratch and still lose my work without warning when I am editing a page as follows

1. Tools
2. Define Pages Editor
3. Wait 15 minutes or more
4. Save
5. ... I am asked to log in again and my changes are gone.

Am I going about things in the wring way?

Thanks in advance.

My bad, for parroting the statement made by the last module updater instead of verifying before "speaking" -- you'll need to install this plugin (the previous version uploaded by DrByte) for this function to be present in all current Zen Cart installations.

Trying to look into this, but a thread was begun identifying issues with this module (using latest) for an admin user that is not given superuser permissions while logged in to a ZC 1.5.4 site. Thread: https://www.zen-cart.com/showthread.php?t=217827

Admin Logs have repeated "attempted access to unauthorized page [keepalive] for legitimate admin user.
This admin user is not a 'superuser', ie: has restricted permissions.
SuperUser admin does not cause similar log entries.

I am getting the "We are unable to connect to the server. Your work may be lost....." alert. It's super annoying, so I disabled the "alert('<?php echo TEXT_KEEPALIVE_SERVER_UNREACHABLE_MESSAGE1;?>');" code to no ill effects.

I have noticed, though, that even when I click the "Yes, Keep Working" button, the header on the site continues to countdown, until it says "!!Expired Session" But It's not actually expired. Just the page's header says that. And the countdown isn't even consistent after clicking keep working, then navigate to another tab. It will hang out at like 181 2-3 seconds, 180 for even longer, sometimes flash the pages actual title, then continue counting down at normal speed once the tab is in focus. Once it says expired session, the next time the modal box pops up, it doesn't give the countdown, it says that the session expired and to login.

Yes, this has been an issue for yonks and was first mentioned in this thread in Sept 2013.

I have several ZC 1.5.4 installs on my local dev server (PHP 5.5.9, Apache 2.4 etc, Ubuntu OS, etc) and it happens only on one site, the others are not giving me the error. I did core file comparisons left, right and center but can't pin-point the cause of this annoying error. All the core files in admin are the same in all sites.

Now I am thinking that there may be a clash with some other jscripts (from installed mods) which could produce that message..... so my next move will be to (temporarily) kick out all other non-core scripts from the admin/includes/javascript folder, test without them and add them back one by one. Tedious, but it may throw a light on this .... eventually.

I'm getting to this discussion a few months later but I hope it's useful to others.

I've just implemented the Keepalive Timer module in the admin area and I had the same problem where the keepalive.php page was being called through ajax and kept falling 5 times until the TEXT_KEEPALIVE_SERVER_UNREACHABLE_MESSAGE1 pop-up.

I found it has to do with the $.ajax timeout value set to 450ms on line 170 in the /admin_area/includes/javascript/jquery.idletimeout.js file.

Increasing that value to 3000 (3 seconds) solves it for me.

@DrByte I'm wondering if calling the keepalive.php every minute during 10 minutes isn't defeating the purpose of having a 15 minutes session? Every time the keepalive.php script is being called, I see the expiration time on the session increase.

If "idleAfter" is set to 600 seconds (10 minutes) before actually being defined as idle, it means the actual session still has 15 minutes to go. So, one can leave its computer idle for 10 minutes and still have an active session expiring in 15 minutes for a total of 25 minutes?

I may need to tweak it a little, the company I work for are pretty serious about PCI. Thanks for the module!

I know this sounds like a dumb question, but wouldn't it be much simpler to allow the "Admin Session Time Out in Seconds" be set to infinite?

The Admin Keep Alive timer only tells you ever so often that you are going to be timed out, and if you don't respond soon enough you will get logged out.

I like to have the "who's online" page up just to pop in now and then to see if there's anyone there.

You loose your PCI compliance.....

If you want that to happen then you only need to set "Updating Manually" (top right hand box) from the default "OFF" to 1 Min.
