hello, I have a problem with my site ( latest zenphoto ) and zpmobile theme, it is very slow between 10 seconds and 1 minute (sometimes it just turns in circles ) to display an album or picture.
Can you help me?
The website address is wallstock.fr

sorry for the English translation , this is a google translation

If you images have not been cached it might take a while to generate the sized images. Especially if you use very big images. The only fix for that is too use the cache_manager to pre-cache theme. Even that may take a while which is dependend on your server's speed.

Also try the static_html_cache plugin that might speed up things.

plugins were already activated for a long time but nothing changes , it's still too long even for pages already in cache.

if I use a theme like Zenpage , my site is working normally and without delays

I not sure if this is the cause but firefox plugin webdevelopper displays an error

The issue you posted does not really tell anything as that is an internal chrome message.

zpMobile is more or less pure jquerymobile. However, I see you switched to another theme and the site appears very slow to me.

Maybe your server is a bit slow or just encountering some traffic peaks right now? I don't see the static_html_cache being enabled actually.

I tested several solutions by removing or putting plugins/themes and I finally found that I was an idiot , my Java version was outdated.
Now it is much faster

thanks acrylian

Not sure how an outdated Java version on your server would affect a PHP application like Zenphoto?

you're right , I have another problem but I do not know which
I put the theme libratus static_html_cache but does not work when it is activated

I put zpmobile , cache works but jquery works is very slow
even stranger, if I click on a thumbnail , jquery does not work (or very slowly), if I right click to open in a new tab, it works

The static_html_cache is theme indepedent but in case your are logged in you don't get cached content.

Regading zpMobile: Does the demo on our site work for you? It seems you have quite big images 1920x1200px. Might be that is is too much for your server. Take a look here: http://www.zenphoto.org/news/problems-with-albums-and-images

I ssee one JS error related to the rating plugin. That always has not really been compatible with zpMobile. Try to disable that.

if I use the zpmobile theme static_cache running smoothly but jquery is very slow : several minutes to open an image with a left click (right-click opens it in about ten seconds)

if I use the theme libratus left click opens the picture correctly but the static_cache plugin does not work at all

I disabled rating, nothing has changed

I solved the speed problem for zpmobile theme by downloading an archive of zpmobile and it works perfectly .

may be a corrupted file but I do not know which

Good you could solve it!

the problem is not with the theme because after delivering advertisements and the text in the theme , the site is again slow.

These are the only adaptable adsense ads that do not work very well with jquerymobile what caused slowdowns

I install this time zpbootstrap and for the moment, everything works without slowing except those adaptable advertisements that are not displayed on the computer screen within refresh page
