I have just finished trying to update mautic from 1.2.4 to 1.3 but unfortunately gave me error so I deleted mautic and started clean install of mautic 1.3 but it did not install yet 1.2.4 install easily with no error and setup in no time in the same domain and hosting. php version is 5.4.43 and mysql is 5.5.42 . Any suggestion is very much appreciated.
