I did update mootools-core.js along with phoca gallery component and slideshow plugin to the latest versions. I am using joomla 1.7.0 but that did not fix the problem.. Anything else you could suggest?
Ow, I did notice that in html there are two div's with class gallerylayer so the plugin is doing calculations twice, and seems to be loaded twice, I am using the line {pgslideshow id=4|width=940|height=250|delay=5000|image=O} along with articles anywhere plugin, maybe they are compromising each other somehow..
As a quick fix I hid the first with display: none; but that still is not good solution because calculations are done twice and loads the website more. Please help
