I tried to put the website offline, so we can work on this in the background... but I still get the same error

Best regards

Good morning seems like there is a problem with the "theme". Although I thought everything worked perfectly of PHP8.1 When we switch back the PHP version tot 7.4 everything works. In the opening topic, there was a screenshot with all the errors. Mostly it was SPPB

Please share the issue page link where you see it. I will check it.

Good evening Ofi As I said before, I changed my settings back to PHP7.4. When I put them to 8.1 I get the error. The screenshot of the error is in the first topic

Please take a full site backup with Akeeba Backup in ZIP format and share here. Follow this tutorial. I will check it on PHP 8.1 on my end.

Hello guys,

I am running on PHP 8.1 with SPPB 3.8. without troubles. I updated SPPB to 5.0 and have the same issue. I had the issue in productive enviroment, where I restored the backup and also have it now in XAMPP on my local pc.

TypeError: Unsupported operand types: string + int in C:\xampp_8_1_17\htdocs\joomla\zkp23_10_22\templates\flex\sppagebuilder\addons\tab\site.php:135

$output .= '<a data-toggle="sppb-tab" id="sppb-content-'. ($this->addon->id + $key) .'" class="'.($style == 'custom' ? $nav_text_align : '').' '.$icon_block.'" href="#sppb-tab-'. ($this->addon->id + $key) .'" role="tab" aria-controls="sppb-tab-'. ($this->addon->id + $key) .'" aria-selected="'. ( ($key==0) ? "true" : "false").'">'. $image_top . $image_left . $icon_top . $icon_left . $title . $image_right . $image_bottom . $icon_right . $icon_bottom . $subtitle .'</a>';

The variable &key is empty. If I set in debugger $key=1 for my 1st page with the Tab, then it works. If I set $key=2 in other page, it works too.

The only one possible solution is delete the Tab object from the page and add it as clear new object. I tried it with new tab and it works.

Good morning

4 months later.... still no solution

In the meantime... I updated the versions of Joomla and all add-ons. I still get the same error. I tried to transfer the website to a different domain... same error.

At the moment, the website is still running on PHP7.4.33.

I get a notification to upgrade to J5, but that's not even working, probably because of the old PHP version.

Apology for the delay. Please keep a full site backup first. Then uninstall SP Page Builder and install the latest version again. Then check your issue.

Good afternoon if I uninstal SPPB.... will all pages be gone then? There is almost no data in "normal" content in Joomla.

Just asking before I start uninstalling :)

Generally, the data remains there. But I would like you to keep a backup for safety.
