Ciao Laura,

In general, I don't recommend using SPPB 5.x inside Joomla 3.10.

Maybe eaiser will be recover site from backup and keep SPPB 3.8.10 as you probably had.

Joomla 3.10 is NOT SUPPORTED anymore please consider Joomla upgrade.

In this thread https://www.joomshaper.com/forum/question/40397 This supper has suggested me to use 5.4.6 now I have to go back until 3??

I shared you my opinion based on my expirence. Becuase v5.4.6 is also "old" from Jan 2025, and now we have July and v5.7.1.

I can take look inside admin area, but if SPPB 3.8 worked without any issues - keep it.

Any news about this?

To be honest we didn't fully test that version with J3.10 becuase even then J3 was not supported. You are using J3 on your own risk.

In your case probably problem is from old plugins, for example, that one: plugins/system/marcosinterceptor/marcosinterceptor.php

and too new PHP version !!

J3.10 don't fully support PHP 8.2 and it causes many problems, errors, Deprecated messages. As Joomla webmaster you should know it from J! documenation. Please for testing period disable mentioned plugin, switch to PHP 8.0 and recheck. There are important changes between PHP 8.0 vs 8.2.

I enabled showing errors in Joomla Global Configuration, but I cannot disable that anymore, please edit configuration.php file and change from "maximum" to "none"

public $error_reporting = 'maximum';

I will talk with our developer in next days about that. Thanks.

I have fixed it my self.

People need the fix can follow the tutorial at this link: https://drive.google.com/file/d/1uIvkkyFE07T7O4_AXG3rC6_IFALuklSl/view?usp=sharing

Thanks

Yes. The situation is with joomla 3.10.12 and sppb 5.4.6

So, this topic is only for Joomla archaeologists, stuck with the old versions. No offence.
