Having problem with the above svn issue when you do an svn update? check my solution below.
[user1@host production]$ svn update common.php
svn: Can't open file '.svn/text-base/common.php.svn-base': No such file or directory
[user1@host production]$
[user1@host production]$ touch .svn/text-base/common.php.svn-base
[user1@host production]$ chmod 777 .svn/text-base/common.php.svn-base
[user1@host production]$
[user1@host production]$ svn update common.php
Restored 'common.php'
E common.php
