What does pagespeed do on my website?

[Johan Jonker]

There are a few problems with the caching of my site in combination with Chrome.
While searching for solutions I discovered that my site is processed by a pagespeed tool and for instance the html code of an image looks like this:

<img width="200" height="288" pagespeed_url_hash="2952880927" alt="" src="http://www.pghouten.nl/images/200x288x2 ... png"></img>

I cannot remember installing a pagespeed tool in joomla and suspect the tool from causing a lot of troubles like increasing cache problems.

Can anyone explain where this pagespeed comes from?
Is it standard part om Joomla 2.5?

kind regards Johan

Problem 1: after changing an article (e.g resizing an image) in the backend, Chrome does not show the changes after a reload of the frontpage. Caching in the Joomla site is off. Deleting the cached images in Chrome does not solve the problems.

Problem 2: invalid token when I log in on the frontpage.

Problem 3: The complete template is missing until I delete the caching images in Chrome.

problem 4: Some images are missing in Chrome. Firefox does show them.

Problem 5: When I delete an article, Chrome keeps showing it in the last news category overview. When i select it an 404 error occurres.

Problem 6: Often when I select "Show website" in the backend. An server error (505) occures. I have to restart the browser to see my website of use a different browser.

This looks like an apache module, you should probably contact your hosting company to disable it if you like so.

Hello ionut,

Thanks for your reaction. I checked my hosting company and they have this module installed for years. I can deactivate it in my htaccess by this code:
# Turn mod_pagespeed on/off for this domain
ModPagespeed off

It helps to solve some of the problems (1, 3, 4, 5 and 6)

Thanks
