[Loris-dev] Unable to Access the Front-end

Hi Dave,
I just realized that there should be no forward slash before it since there is a forward slash at the end of the base path which I forgot to add at the beginning. Sorry for bothering you and thank you very much for your help!
Best,
Aaron

Hi Dave,
It is working! Seems like it is because the path wasn't correct. We forgot to add the forward slash at the end of the path. Very much appreciated your help.
There is also one question I will like to ask which might be an error too. I was trying to debug it by myself before knowing the missing forward slash. I got an error log like this.

I found out that the path to find the module in the Module.class.inc file wasn't correct. I added a forward slash before project and modules and the error was gone.[cid:6f4d8945-b5a6-4ac0-9c29-ba9d544cb59b]
Should there be a forward slash before project and modules? Thank you in advance and Happy Thanksgiving!
Best,
Aaron

This sometimes happens if the base path config setting isn't set correctly.
Can you run the SQL: SELECT * from Config WHERE ConfigID=(SELECT ID FROM ConfigSettings WHERE Name='base');
and see what the result is? Also check if there's a xml tag named <base> in the config.xml (which would override the database value)
The value should be the directory where you installed LORIS including the trailing slash. ie `/var/www/loris/` (errors like this sometimes happen if it's set to `/var/www/loris`)
If that config value is correct, it could also be a filesystem permission issue. Make sure the files' unix permissions are readable by apache and the directory permissions leading up to it are all executable by apache (including the /var and /var/www).

Hi,
Thank you very much for the help. I did see there was a typo in my config.xml file. However, the front end is still inaccessible after I corrected the typo. I also throw our XML file into the XML validator but there is no syntax error. Below is the new error log I got after fixing the typo.

It seems like there are some other errors that LORIS is trying to display via frontend but can't find the template in the system. Though, I did find 404.tpl and 500.tpl under /var/www/loris/smarty/templates/ directory. Also, the path to load the config.xml somehow was fixed by itself as I didn't see the error message again in the log file.[cid:184a5021f97cb971f161]
Thank you in advance!
Best,
Aaron

Hi Aaron,
After resolving the ../ references the path looks like it's correctly looking at /var/www/loris/project.xml but the errors suggest that the file isn't valid xml.
It looks like from the second line <item value="V2">V2 label description</tem> that you made a typo in the V2 and missed the "i" in the closing tag for the "item" tag.

Good morning,
Hope this email finds you well. Our team is trying to set up the LORIS system for research. It was working before but somehow, we aren't able to access the front-end. Below are some snips of errors from the loris-error.log under the /var/log/apache2/ directory.

It seems like the path to the config.xml isn't correct. It should be /var/www/loris/php/libraries/project/config.xml, not /var/www/loris/php/libraries/../../project/config.xml. Where could I change the path?
Any help would be much appreciated.
Best,
