Setup error: Undefined constant PERCH_ERROR_MODE
When I run setup, I get the following error:
Warning: constant(): Couldn't find constant PERCH_ERROR_MODE in [path]/perch/core/lib/PerchDB_MySQL.class.php on line 44
It happens after the user creation step in the setup. This seems very similar to this question/post/answer https://forum.grabaperch.com/forum/04-07-2017-warning-constant-couldnt-find-constant-perch-db-password, but it seems very odd that I should need to edit the config after it's been created (unless I want to customize something). The setup seems to have created the tables, but the user table is still empty. I also can't seem to find anyway around it other than hacking the user in manually (you don't want to know).
Any ideas how to solve it?
Here's the full error:
( ! ) Warning: constant(): Couldn't find constant PERCH_ERROR_MODE in [path]/perch/core/lib/PerchDB_MySQL.class.php on line 44

Have you removed details from diagnostic report [path] or is that the actual output?
I replaced the actual path with
[path]...no need to know my server structure :)Add PERCH_ERROR_MODE, 'SILENT' to configure.php and see what happens.
So, here's the problem: I can add it to the config (thus creating the non-existent config) but then the setup process immediately overwrites the file and we're back at square one. I can kinda hack around by refreshing and going back and forth through the setup process, but it seems extremely odd that this would happen at all. I would think it should either check for the constant's existence before using it or ensure it's defined somewhere.
It looks like the constant is defined when using the runtime, but not always during setup (and maybe not at all).
What is your dev environment? I am guessing windows??
Nope, it's Linux (CentOS) with Apache/PHP-FPM 5.6/MySQL.
That's one of the very first constants that gets defined - I can't think of a way your database would be accessed before that's defined.
What's the URL when you get that error?
