FlatPress Github 3049 - Debian 12.13 Nginx Server, PHP 8.5.2

[laborix]

Okay, first test with FlatPress Github 3049 on an Nginx server with WordPress defaults:

location / {
# WordPress web hosting config for Nginx servers
try_files $uri $uri/ /index.php?$args;
}

The current FlatPress Github 3049 is installed in the /(root) folder, and the setup is running.
Logging in and activating PrettyUrls works.

Selection
(*) Automatic
(*) HTTP Get auto
Example: /?u=/2024/01/01/hello-world/
(*) Pretty
Example: /2024/01/01/hello-world/

works. Then, under Posts, attempt to create a post. The following happens.

Code: Select all

Fatal error: Cannot redeclare function smarty_validate_criteria_notEmpty() (previously declared in /var/www/html/fp3049/fp-includes/fp-smartyplugins/validate_criteria.notEmpty.php:36) in /var/www/html/fp-includes/fp-smartyplugins/validate_criteria.notEmpty.php on line 36

Any idea what's going on?

Hello Matthias,

The same Smarty Validate Criteria file is loaded twice – but from two different directories.

First loaded from: /var/www/html/fp3049/fp-includes/fp-smartyplugins/validate_criteria.notEmpty.php
Then again from: /var/www/html/fp-includes/fp-smartyplugins/validate_criteria.notEmpty.php

Code: Select all

Fatal error: Cannot redeclare function smarty_validate_criteria_notEmpty() (previously declared in /var/www/html/fp3049/fp-includes/fp-smartyplugins/validate_criteria.notEmpty.php:36) in /var/www/html/fp-includes/fp-smartyplugins/validate_criteria.notEmpty.php on line 36
Stack trace: #0 /var/www/html/admin/includes/panels.prototypes.php(141): AdminPanelActionValidated->onsubmit() #1 /var/www/html/admin/includes/panels.prototypes.php(218): AdminPanelAction->exec() #2 /var/www/html/admin/main.php(96): AdminPanelActionValidated->exec() #3 /var/www/html/admin/main.php(218): main() #4 /var/www/html/admin.php(5): require('...') #5 {main}

Wild guess: You have (at least) two FlatPress code trees, and NGINX/PHP-FPM "mixes" them in one request. Apache typically does not show this because DocumentRoot/Script paths are often more consistent there.

Not "PrettyURLs" per se, but path/root mismatch:
- NGINX executes some PHP files from installation A,
- but then includes parts (Smarty plugins) from installation B,
- and as a result, smarty_validate_criteria_notEmpty() is declared twice -> Fatal.

Possible causes:
- Two installations exist in parallel (/var/www/html/… and /var/www/html/fp3049/…) and NGINX sometimes points to the wrong one.
- In the NGINX configuration, root/fastcgi_param SCRIPT_FILENAME/try_files are not consistent (e.g., different root in location / than in location ~ \.php$).

- Symlinks/bind mounts + $document_root instead of $realpath_root -> PHP sees "different" physical paths.

Check whether both directories exist:
- /var/www/html/fp-includes/...
- /var/www/html/fp3049/fp-includes/...
Decide which installation is the real one, and:
- remove/move the other one, or
- set NGINX root explicitly to exactly this one.

Code: Select all

root /var/www/html/fp3049;   # or /var/www/html

location / {
	try_files $uri $uri/ /index.php?$args; # or try_files $uri $uri/ /index.php$is_args$args;
}

Best regards,
Frank

So, complete reset of the Nginx server and provision of empty space. Transfer FlatPress Github 3049 and install in the server /(root) folder. Quick test works, log in and play through new posts and change PrettyUrls settings.

( ) Automatic
( ) HTTP Get auto
( ) Pretty

These three settings work. Tested new posts, search, click on categories, and pointless clicking through

So you could say that the WordPress location recommendation also works with FlatPress PrettyUrls Standard.

Code: Select all

location / {
    # WordPress web hosting config for Nginx servers
    try_files $uri $uri/ /index.php?$args;
}
