OK, just sifted through the settings, activated Root folder BPS mode, and I think I have it all right.
Just one thing seems to be lingering, and that is an issue with the PHP Error log file path.
BPS says the log file is writable, but there is a discrepancy between the file path seen by the server (which appears to be the old path on regular shared hosting) and the recommended file path, resulting in a error message at the top of the screen “<span style=”color: #fb0101;”>PHP Error Log Path Does Not Match.</span>”
When it’s set to the recommended path I see the pre-existing errors in the log, but testing with the recommended path does not print the test error to the log file. With this setting I see both the Last Mod time in DB and in the file, and they agree.
Testing with the path seen by the server generates an error “PHP Error Log File Not Found! Either the PHP Error Log Folder Location has not been set yet or the PHP Error Log Folder Location path that you set is incorrect. Click the Htaccess Protected Secure PHP Error Log Read Me Help button for more info,” and that is all I see in the log. With this setting I see only the Last Mod time in DB, with no time showing for the file at all. I’m pretty sure this path is to the old error log on regular shared hosting.
I read the Read Me note, but I don’t see anything that addresses this situation specifically so I’m not sure how to proceed.
