Site still breaks every 30 days or so

The assistant did change it back. Am still looking for where the hosting company keeps the error logs.

I added the ability to view the error logs and even though it's only been a few minutes, here is the first list of the error_log file:

Does this tell you anything?

There is a minor issue with a FormBuilder template, but nothing serious and absolutely nothing that would break the site.
The only errors that we will need to account for are the ones occurring at the time the site breaks... Those will be difficult to chase, but should happen and should be the ones that may give some clues about your issue.

Thanks, Jo.

I will check it next time it breaks...which should be tomorrow afternoon.

I'm seeing a similar thing. My site is breaking periodically, which results in the site reverting to the title "CMSMS Site" and the templates generally looking messed up.

Going into admin and clearing cache fixes it, but obviously this has to stop happening.

This is what I'm seeing in the PHP log, but it may be a symptom as opposed to a cause.

Troubleshooting a bug where you have now clue where to start you have the exclude parts that work/doesn't need, and thus continuously reduce the search area.

Start by disabling modules that you don't use/need. Always use the latest versions! Check error logs, access logs, use debug mode, etc. etc. Without this, it is looking in a glass boll and you can only guess what might happen.

But the chance it isn't related to CMSMS is very lickely. Have you contacted your webhost? Have you moved the website to another host/server and does it occur there too?
Is your website/server hacked?
...
...

Might have to do a blog on this some day...

JamesT · Post by **JamesT** » Mon Jan 02, 2017 1:06 pm

It's going to be tough to diagnose, I agree. The thought that it might be webhost related also occurred to me; the rise of "cloud hosting" doesn't necessarily feel good to me whereby files are scattered across different servers, sounds like a synching nightmare to me.

I always keep CMSMS and modules rigorously up to date though, and none of my modules are what I would consider "obscure". Disabling modules isn't really an option when they are all needed in production.

As for the webserver being hacked, not to my knowledge.

Ok, this is a stupid bug on Captcha which only happens on upgrades (not sure why it only happens on some upgrades though) ... Being a module with very few options/settings uninstalling and reinstalling it can be an option and fixes this particular Captcha issue, just make sure you keep the settings somewhere so they can be restored after.
This however is (or should be) unrelated with the original topic afaik. The Captcha error should happen every time it is requested on a form or page, not only on specific time cycles and not on every page.

JamesT · Post by **JamesT** » Mon Jan 02, 2017 1:48 pm

The Captcha error disappeared completely after the site cache was cleared and the "broken site" issue was fixed, so it appears to have been a symptom of the "broken site" issue rather than anything else.

Jo,

It just now broke again. I've attached the error log and am pasting in the System Info. As I mentioned, I did update to 2.1.6.

Clearing the tmp/templates_c folder fixed it, temporarily.

webguru,

Do you ever see any of these?

Code: Select all

[02-Jan-2017 17:47:01 Europe/London] PHP Notice:  unserialize(): Error at offset 126591 of 359767 bytes in /var/sites/m/m.co.uk/public_html/lib/classes/internal/class.CmsTemplateCache.php on line 67

I see them happen occasionally and I wonder if it can lead to corruption in templates or something.

webguru · Post by **webguru** » Mon Jan 02, 2017 8:06 pm

Not that I've ever noticed.

In general this is a harmless warning.

But what *might* happen here... You have the form in the footer of the website and not only on a contact page. So each page view will generate this warning! Having a rather busy website this *might* have an effect on the server process...

It is simple to fix, check your form template for:

Code: Select all

{if $captcha_error}

and change it in something like

Code: Select all

{if isset($captcha_error) && $captcha_error}

If it is not the cause the error log is cleaned of these warnings and it is simpler to see other errors/warnings. Worth a try!

webguru · Post by **webguru** » Tue Jan 03, 2017 4:59 pm

Thanks, Rolf...I made the change and will keep an eye on it.

Are there any other options for Captcha that you know of? If this is the culprit, what do I do?

Rolf · Post by **Rolf** » Tue Jan 03, 2017 10:51 pm

If you still get (many) errors from the Captcha module, perhaps better disable the module because it also is shown each page load.

Easy (temporary) alternative is a honeypot https://www.cmscanbesimple.org/blog/hon ... ormbuilder
