modman Posted April 28, 2022 Share Posted April 28, 2022 Hi I get this error when upgrading from version 4.5.4.2 to 4.6.12.1. First I tried the automatic update in ACP, then I downloaded all the files again and uploaded overwriting the existing ones. The error remains the same. The site is not reachable now, I get the error attached. I've checked the file permissions and they don't seem to have any problems. For example the first error refers to the file "/applications/nexus/Application.php" The folders and the file in question all have the "0777" permission, yet it persists on this file.

modman Posted April 28, 2022 Author Share Posted April 28, 2022 I've tried to delete the "Nexus" folder in Application but the error remains the same. Link to comment Share on other sites More sharing options...
Mark H Posted April 28, 2022 Share Posted April 28, 2022 That error means the files for Commerce (nexus) are not the correct version, or they are inaccessible by the software. (Also, don't blindly set files and folders to 0777 permissions, that may cause an error by itself, if the server is using suexec or suPHP. Change to those permissions only if specifically told to do so.) For the possibility of wrong versions... please download a fresh copy of the software from the Client Area, then upload all its files (not just a partial set), overwriting when prompted and making cure all files transfer without error. Also check to make sure the files and folders are owned by the same user, generally the server account which actually runs the software. Link to comment Share on other sites More sharing options...
Marc Posted April 28, 2022 Share Posted April 28, 2022 The issue there is that you have commerce installed on a site which doenst have a license for it. Not sure if you have switched your licenses at some point. You need to uninstall that application and start the upgrade again Link to comment Share on other sites More sharing options...
Mark H Posted April 28, 2022 Share Posted April 28, 2022 Oh, yes, I missed that. As my colleague noted you are trying to install Commerce but do not have a license for that app on the site your screenshot shows. It needs to be fully uninstalled from the ACP, then an upgrade performed. The other option is to purchase a copy of Commerce for that license, then you can use the app there.
