Not working (critical error) on WP 6.0.3-6.1.1

[Bards]

It is not working, it is reporting a critical error after the installation of the lite (free) or a pro version...

Any similar experiences or known solutions?

Hi @Bards

Strange issue. Could you please check or share your error.log with lines about fulltext-search plugin? There should be any records in this case.

Could you share any screenshot with the critical error message?

Thanks!

[Bards]

Thank you for your fast response...

Sorry, it is a Fatal error, not Critical...

Here is my debug

It is a Serbian Cyrilic site, but on the other site (older one same Cyrillic) plugin still works perfectly.

Thx

Hi @Bards

It's a very strange issue. Look to the error message, it says "Call to undefined function error_log()" that means "error_log" function was not found. However it's a native PHP function which should be present always.

https://www.php.net/manual/en/function.error-log.php

Why it's not defined? It can be your server or your hosting issue. Could you consult your hosting provider's support for that?

Also there is a link to this code from WPFTS core:

			$q = 'select 
					count(*) n_inindex, 
					sum(if ((force_rebuild = 0) and (build_time != 0), 1, 0)) n_actual
				from `'.$idx.'index` 
				where `tsrc` = "wp_posts"';
			$res = $wpfts_core->db->get_results($q, ARRAY_A);

As you can see it's a very simple code that basically should not trigger a critical error.

Please could you tell me which WPFTS version you tried and which PHP version is used there.

Thank you!

[Bards]

Thank you for this... Your message directed me to check php version that is used on the website.

I have more websites on the same server, and they all use PHP7.4 but this one was use PHP8.1. When I switched back to 7.4, all is up and running again

The conclusion is: It doesn't work with PHP8.1 (I didn't check PHP8.0)

Thank you.

Hi @Bards

Okay could you still tell me which WPFTS version is there?
Basically it can be too old, because latest WPFTS version DOES support PHP8.1.

[Bards]

The version is 2.46.180 (I think this is the latest one)

[EpsilonAdmin]

Hi @Bards

Officially yes, 2.46.180 is the latest. However there is a pre-release version 2.49.208 that have a lot of fixes including fixed support for PHP8.1+

I've sent you that version to the private chat, please install it to replace 2.46.180 and try with PHP8.1.
