For some reason, this is a site used for building new sites as staging site. For some reason have loaded a new install, and standard components we load on all sites. Tried running a backup as per normal and it stalls at 25% and goes no further, waited 30mins and no change. Have reinstalled Akeeba Pro just in case, same issue. Always gets stuck showing file as per screenshot and the only way out of this is to hit the back button which breaks the stall. Will include log file as requested also.
