About: carolm

I live in Sydney and have 2 blogs that started early in 2012.

My Second Million documents everything I learn along the way from complete Blogging Beginning to mega stardom and untold's a work in progress.

This regular documenting and updating process has transformed My Second Million from a single 'Welcome! Page' to a large Content Resource, full of useful WordPress and Blogging information. And it grows every day as I learn new stuff and tell my readers all about it.

I'm currently learning about s2member plugin! My first 'How to' Post on s2member plugin is about to go live - once my Affiliate link comes through.

My other website is Addiction Rehab Now: It provides reliable, evidence based information and non-judgmental support for anyone who has an interest in any sort of addiction.

I disabled and deleted the WPStatsDashboard, disabled the Quick Cache, totally deleted everything in the wp-content/cache, changed all the permissions to read, write and execute.

Made Permissions 0777. Enabled Quick Cache again. Refreshed cpanel – Mutex Lock still Zero KBs. Logged out of site, still no green text.

So, it’s not a clash with the WPStatsDashboard plugin.

The problem is still that I don’t have a Mutex Lock of any sort. Any ideas why, or how I can fix it?

I deleted all the entries in wp-content/cache, except there was one there for my WPStats Dashboard plugin.

I didn’t want to delete that because it is useful and links in with the Jetpack plugin which is also useful.

I didn’t uninstall the Quick Cache before clearing the cache, and it immediately started to be repopulated with files from QC. But the Mutex Lock file still shows Zero KB. And still no green text in the logged out Page Source HTML.

Would it help if I disabled the QC plugin, cleared the cache again (but leaving the WPStatsDashboard file – it contains 2 files of letters and numbers) and re-installed Quick Cache?

Or do you think it’s the WPStatsDashboard file that is preventing the QC plugin from working?

I also checked the Permissions: they were set to
Read: everything.
Write: user only.
Execute: nil.
I changed them all (User, Group and World) to full read write and execute but it didn’t help.

Any advice?

Ha! I see what Permissions are! But I’m still going to get my Host to do the deed.

Thanks Jason, I’ll have a look at those files, but I will get my host to follow your instructions – I don’t want to mess with stuff I don’t understand.

For example: what is a Permission? You don’t have to answer that, but it shows you how helpless non-geeks are when something goes wrong! We never understand the answers – well, almost never.

I’ll get my Host people to do what you advise.

And I will let you know what happens.

Thanks for your help!

Thanks for the reply Eduan.

Those trouble shooting tips from the Knowledge Base relate to the S2member plugin. And I’m happy to report that the S2member plugin works brilliantly on my site. I wrote a rave review about that plugin too, including a ‘How To’ on the MailChimp integration.

I will be interested to know if Jason has any ideas on my Quick Cache problem – I haven’t been able to find any threads here that mention problems with Mutex locks.

If I can get this fixed, I will be amending my Review of Quick Cache to include a ‘How To’ about how it was fixed.

Hi Eduan, you are supposed to know that the Quick Cache is working by logging out and looking at the HTML version of a page.

You are supposed to see green text at the end of the HTML Code that gives you data about what Quick Cache is doing and how it is working properly. And I don’t have it there.

Also, that extract from my wp-content/cache/advanced cache actually says that it isn’t working because something called a Mutex Lock couldn’t be found.

Also if I test my site with online website checkers, they say that my website has no cache.

I’m stumped because I did everything as I’m supposed to, and yet, the cache is not working.
