I have just installed a fresh copy of ImpressPages 4.5.1 and I am getting the following error after install:
require(/var/web/testsite/public/pagesdemo/Theme//main.php): failed to open stream: No such file or directory in /var/web/testsite/public/pagesdemo/Ip/View.php:111
Fatal error: require(): Failed opening required '/var/web/testsite/public/pagesdemo/Theme//main.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/web/testsite/public/pagesdemo/Ip/View.php on line 111
I can confirm that write access was given to the proper directories as I made the entire structure www-data.www-data read/writable (as this is a test environment I am not concerned about any security at this point).
As you can see in the path however it is showing "pagesdemo/Theme//main.php" which to me is indicating that somewhere it missed definition of the Theme (thus is blank).
Is there a way to set this theme manually (where is the configuration? database? config file?)
The theme can be set in the database by creating a following record:
Plugin: Ip Key: theme Value: "Air" //Quotes are important. As this must be json'ed value.
Looks like reinstalling would be also not a bad idea.
