Hi there. I've been investigating slowdown on my websites. I only buy Joomla 51 templates because they are the best but I have a question I cannot seem to answer

3 of my sites are showing debug errors: trying to load menu.css, such as http://bearmakers.com.au/templates/j51_avenue/css/menus.css. I can see this when I load the sites with Chrome and press Shift Control I to open the debugger and click Console. The template doesn't come with a menu.css so why is it trying to load one? It also fails to load a font. Bluelens.com.au fails to load http://bluelens.com.au/templates/j51_clarity/css/.css which isn't even a valid filename.

The weird thing is that I search thru all the files and I remove any reference to menu.css (in template.css) and it still happens. And I don't know why it fails to load a font - I search for this in the template files and it doesn't appear.

When I change to another template like the stock ones, I don't have this issue, so I am sure it's not the page content.

The following sites are all affected.
bearmakers.com.au
pixielandparties.com.au
bluelens.com.au

Are you able to provide a clue as to what is calling out css/menu.css or css/.css, and where to find these fonts that are failing to load?

Thanks as always, your templates are the best.

Tim
