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

Wed Nov 23 04:02:03 EST 2022

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:2260ab22-b5a5-46c8-9828-84261b9d78c6]

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,
Aaron Chen
