However, I am also a little concerned by the error message screenshot you have shown as well. Normally AtoM has its own custom 500 error display page, that looks like this:
What you have shown appears to be the default Symfony error message page (Symfony is the PHP framework we originally used to build AtoM). I have personally never seen the default Symfony error message displayed in AtoM before.
One additional thing you could try doing is recompiling the default Dominion theme, to make sure all visual elements are displaying as expected.
If you have installed using the downloadable tarball from our website (
Option 1 in the installation documentation), there are a few additional steps. We normally provide the CSS pre-compiled in the tarball, so the dependencies needed to recompile the CSS are not installed. We can install them like so:
- sudo apt update
- sudo apt -y install curl
- sudo apt install npm make
- sudo npm install -g "less@<4.0.0"
You should be able to ignore any warnings received during installation. Once installed, we can recompile the default themes with the following commands:
- sudo make -C /usr/share/nginx/atom/plugins/arDominionPlugin
- sudo make -C /usr/share/nginx/atom/plugins/arArchivesCanadaPlugin
Additionally, there are some common maintenance tasks that can resolve many issues, and shouldn't do any harm even if they are not needed. Try regenerating slugs, rebuilding the nested set, clearing the application cache, and repopulating the search index. See:
You can also try restarting PHP-FPM. Instructions for restarting the job scheduler have already been linked in the forum thread above. For PHP-FPM, see:
Don't forget that your web browser has its own cache as well. I recommend either clearing this, or else testing in an incognito/private browser window (where the web browser cache is typically disabled by default) after you have run all maintenance tasks and service restarts.
If this still does not resolve the issue, then please share with us what you find in the web server error logs, and we can go from there.
