It looks like you might be trying to go back to the installer when Omeka S is already installed.
If you want to install again, you need to drop all the Omeka S tables (or create a new empty database and point to that in your database configuration file).
Might be that the xml package didn’t get included in the PHP7 upgrade. Something like this, if you have the server permissions, might do it. Otherwise, ask your server admin to make sure it is available.
Hello there,
I got the same problems at Omeka S installation, when submitting the installation form:
First the error message in red:
There were errors during installation.
Invalid path to file.
If I try to submit again, I arrive at 403 Forbidden first mentioned: seems logical because we try to install Omeka S when it is already installed, as jflatnes pointed out
Then if I try to access my project with localhost/my_project, I get:
0 results
Go to the Admin Dashboard to start working with Omeka S.
And clicking on the link provided to go to Admin Dashboard, I arrive to the login panel, I give my e-mail address and the password I previously chose but I get
Email or password is invalid
And no-email is sent. Thank you in advance for your help
Just an update for those coming accross the same problems:
-On Windows, I still could not make Omeka S function locally, but the installation worked on the the server with the following steps, similar to what you advised to juliewood here: https://forum.omeka.org/t/install-omeka-s/2249/10:
First I got a totally white page
Then I changed the first line in the .htaccess hidden file to SetEnv APPLICATION_ENV "development"
I got a syntax error, even though the server was using PHP 5.6.30 by default
I changed the php version to 7.0.1 for this project, and it worked.
-On Linux, after the install I ran into the same problem of Email or password is invalid and no-email sent, I solved it by creating a new database and editing the database.ini file.
