Hello. I've added an new option in the OPAC user menu where the user can change his reading preferences. The reading preferences is a custom attribute created for the effect. The problem is that the OPAC uses Javascript to change the interface, but when the user select the new option reading preferences the all page is reload. I know that the problem is that I'm not using Javascript to do the page change, but I don't know where and which JavaScript file I need to change. Thanks for your time. Regards. Vitor Fernandes
