Based on that log, check the file /includes/languages/english/extra_definitions/fluorspar/extras.php.

I'm guessing that the file has a ?> at the end, followed by a blank line. If that's the case, just remove that ?>, leaving the ending blank line.

that's not it. There is a php line with a comment inside it at the end of the file. I went ahead and dropped the ?> but it made no difference.

No, you're misreading the error message.
It says the problem is on line 1 of the file.

PHP Warning: Cannot modify header information - headers already sent by (output started at .../includes/languages/english/extra_definitions/fluorspar/extras.php:1) ...

Perhaps your text editor has added a blank line at the top, or has set an invalid BOM (Byte Order Mark).

Might be easiest to just recreate the file. Not by a complete copy-paste of the original, but by recreating its contents.
You could even start by just deleting the file, although I'm sure it contains definitions that the template depends upon, so you will need to recreate what is needed.

Dr Byte, you comment about "recreating" may be a bit over my head. These are all standard ZC 1.5.7a files with the Flourspar template loaded. PHP 7.4.11. I have not created any of the subject files. Please forgive my ignorance.

To add to this, I have found another blank page issue...I happens at the end of creating an account, logging in or logging out. The actions do go through as I can refresh and the account was created, then I was logged in and back and forth. This sounds like the ?> issue but I am not sure what file it would be in.

[g2ktcf]

the checkout button is going to a blank page as well. I did tweak a few text items in one file. I have restored those files to the original ones and the problems is still there.

[DrByte]

By "recreate the file", I meant: read the original file with your eyes, and type its content (with your hands) into a new file of the same name, created afresh for this purpose. The idea being to attempt to eliminate a problem inside the original file by creating it clean as a new file. A simple text-editor is all one needs to do that.

Blank pages are a result of a server-side error. The details of the error are in the server's logs.

Guys, I am going to start a new thread over in the Linux Installation Forum on my above issues/ I thought this was due to templates and changes. However a fresh install of everything says otherwise as I am still having issues.

Thanks

Well, turns out it WAS A FILE IN THE FLUOSPAR TEMPLATE. I do not know the ins and outs of it but Dr Byte mentioned deleting the offending file that was giving me a PHP warning in the debug logs and I missed that advice. All I saw was "recreate the file." After deleting ...../includes/languages/english/extra_definitions/fluorspar/extras.php file, everything started working again. I cannot explain why.

After deleting it. ALL THE BLANK PAGES ARE GONE as well as the warnings. The contents of that file are four lines are

<?php

if (!defined('LARGE_IMAGE_WIDTH')) define('LARGE_IMAGE_WIDTH', '');

if (!defined('LARGE_IMAGE_HEIGHT')) define('LARGE_IMAGE_HEIGHT', '');

if (!defined('MODULE_ORDER_TOTAL_GV_STATUS')) define('MODULE_ORDER_TOTAL_GV_STATUS', '');

if (!defined('MODULE_ORDER_TOTAL_COUPON_STATUS')) define('MODULE_ORDER_TOTAL_COUPON_STATUS', '');]

These do not REDEFINE anything, they should check for a definition and then move on if the value is defined.

Should extras.php be removed from the template or is my install different in some manner?

Again, ZC 1.5.7a, OPC and Fluorspar on Centos 6 server, cPanel 86.0 (build 31), Apache 2.4.46, PHP 7.4.11, MySQL 10.1.48-MariaDB
Perl 5.30.0

Thanks
Chris

I'm pretty sure the file was saved incorrectly when it was created.
Language files need to be saved "Without BOM" ("Byte Order Mark").
Most text editors operate in "without BOM" mode, but sometimes when non-english-speaking people create files they have BOM mode enabled in their editors, and that sets a special character at the beginning of the file ... which PHP treats as text. Outputting that to the browser is treated as sending page-headers ... and when that happens too early in the execution process you get the symptoms you've been posting about: headers-already-sent-on-line-1.
Saving the file "without BOM" (or "not With BOM") usually solves the problem. But if you don't know how to change the "save mode", typing out the file's contents by hand into a new file will probably suffice, especially since you're in Texas, even if you do speak 'merican ... at least it's a derivative of English.
