Hello. There is such problem, apk has created phone application on android, everything works at js but the Quote and Answer buttons cease to work in the application, everything works at the website ideally. screen
As far as I see nothing works on your website. Forum is totally crashed, all AJAX and JS functions affected. All problems come from website optimization plugins. Please disable all plugins which do JS / CSS / HTML optimization and minification. Please disable those for wpForo pages http://ironboy.ru/forum/ * or disable those fully. Please don't use JS and HTML optimization tools for wpForo.
I'm sorry but I didn't follow you. In case if it still doesn't work you should disable the optimizer plugin, then delete all cache and test it again. Maybe the JS specific disabling is not complete or not enough.
