Hello Joachim,

Thanks for your detailed explanation.

There’s no specific limitation on the number of rows or text blocks in SP Page Builder, but in some cases, very large sections (especially within Accordion or Repeater structures) can hit PHP or server resource limits during saving — resulting in a 500 error.

Here are a few steps you can try to resolve it:

1. Increase PHP limits from your hosting control panel or php.ini:

   • memory_limit = 256M or higher
   • max_input_vars = 5000 or higher
   • post_max_size = 32M or higher
   • max_execution_time = 300

2. Save the table content in smaller parts — for example, create two separate accordion items instead of one very large block.

3. Use a Table Addon (if not already) instead of individual text blocks — this can significantly reduce the number of nested elements in the layout.

4. Check the server error log — it might show the exact cause of the 500 error.

If the issue continues even after increasing the limits, please share the error log details or a screenshot of your PHP info, and we’ll help you investigate further.

Best regards
