Intermittent hangs - Newbie

I’m new to Modx but had installed and tested a previous release some time ago without problems. However I’ve just done a new install of this release on the same host I had used before and I am experiencing all I can describe as browser hangs. The install itself went without a hitch but these problems have cropped up since starting to use the CMS. These hangs occur randomly and can occur either whilst I’m browsing the site or whilst in the manager and they happen regardless of browser in use. The only solution is to close the browser and try again after a period of time. As a newbie I’m not sure how to track down the problem and would be grateful in anyone can point me in the right direction.

Many Thanks.

Is this with the demo site? If you are on a shared host it may be an overloaded database or something like that.

It is shared (paid for) hosting but I’ve never had problems before.

It was a new clean install (new database) but I did flag to include the demo site, however I’m the only user so it’s difficult to believe it’s overloaded however maybe I misunderstand, please explain.

Thanks

Have you tried accessing the site from a different computer? Might also be worthwhile checking the MODx demo site for a comparison.

You could also display the php, mysql time on your site which could highlight any slowness / server overloads

<p align="center">MySQL: [^qt^], [^q^] request(s), PHP: [^p^], total: [^t^], document retrieved from [^s^].</p>

Ok, checked on another PC.....Same Problem.

The code you provided gave this result:

MySQL: 0.0053 s, 5 request(s), PHP: 0.6657 s, total: 0.6710 s, document retrieved from database.


It probably won’t help but when I get this hang on Internet Explorer, after a while I also see and error, which is:

"Fatal Error: Maximum execution time of 30 seconds exceeded in ********\manager\includes\config.inc.php on line 61"

***** = path to installed site

Here’s the area around line 61 in config.inc.php


55 // start cms session
56 if(!function_exists(’startCMSSession’)) {
57 function startCMSSession(){
58 global $site_sessionname;
59 session_name($site_sessionname);
60 session_start();
61 $cookieExpiration= 0;
62 if (isset ($_SESSION[’mgrValidated’]) || isset ($_SESSION[’webValidated’])) {
63 $contextKey= isset ($_SESSION[’mgrValidated’]) ? ’mgr’ : ’web’;
64 if (isset ($_SESSION[’modx.’ . $contextKey . ’.session.cookie.lifetime’]) && is_numeric($_SESSION[’modx.’ . $contextKey . ’.session.cookie.lifetime’])) {
65 $cookieLifetime= intval($_SESSION[’modx.’ . $contextKey . ’.session.cookie.lifetime’]);
66 }
67 if ($cookieLifetime) {
68 $cookieExpiration= time() + $cookieLifetime;
69 }
70 if (!isset($_SESSION[’modx.session.created.time’])) {
71 $_SESSION[’modx.session.created.time’] = time();
72 }
73 }
74 setcookie(session_name(), session_id(), $cookieExpiration, MODX_BASE_URL);
75 }
76}

sounds like your host has set php to timeout after 30s of running which helps stop bad scripts on the server. 30s is a bit low.

Create a test.php file on your server and put in

<?php
phpinfo();
?>

Then load up the page check max execution time and have a look at the sessions section it could be a paths / permission issue.

Hi Aaron,

I tried the last bit of code you posted phpinfo() but it just returns an empty page. Am I doing something stupid

In the manager you can run phpinfo in the system info page (under reports).

Ok, took a while before I got around to it but the info from the Modx manager report is:

Might be worthwhile getting your host to check that your website has modify rights to c:\windows\temp so that sessions are created, we had a similar thread before and this was resolved by checking the permissions and re uploading the files.
