Hi,

In general 500 internal error can be caused by many reasons. For sure SPPB Pro 3.8.7 work correctly on Joomla 4.1.5 - tested by many users, and me.

1. What template name you have / version?
2. Do you have any module or plugin that is not Joomla 4 ready. To be sure disable those extra extensions that you are not sure, and check again. This is also common reason.
3. PHP version? It's better to check first on PHP 7.4 then switch to PHP 8.0.x.

Hi Paul. As I mention, I test with a brand new installation, without any other plugin or components, with the same exactly problems. 1 - Template Shaper_helixultimate (no other Joomshaper Template) I build my own site without templates 2 - Only I have in the Migration Webstie is Akeeba Backup what is ok with J4 3 - PHP Ver. 7.4.30

1. Check: error_log file in your root folder / server . what kind of errors you have inside?

2. Is Helix Ultimate plugin enabled?

3. Check also using Joomla default template.

1 - do not show me any error.. just blank file 2 - Yes 3 - I did, same problem (the front view is working in all the cases, the problem is in the admin)

ABout left broken menu - this module should be disabled/uninstalled, it was created for Joomla 3.x only. Just find "SP Page Builder Menu" in list of Admin modules - OFF.

Read tip 15. from >> https://www.joomshaper.com/documentation/sp-page-builder/sp-page-builder-3/troubleshooting#how-to-remove-pagebuilder-menu-in-joomla-4-admin-area

Please check point "4. PHP configuration" > https://www.joomshaper.com/documentation/sp-page-builder/sp-page-builder-3/basic-information-requirements

PHP memory_limit =  256M (512M suggested)
PHP max_execution_time = 180 (300 suggested)

Compare with yours ! Correct if you have lower values in cPanel.

Ok the fisrt step done, disable the menu. Ok

Second post: Allow Url Fopen (allow_url_fopen) - ON (is correct) PHP memory_limit = 128M (512M suggested) (is correct 512 set) PHP max_execution_time = 180 (300 suggested) (is correct 300 set) PHP upload_max_filesize = 5M or more (is correct 128 set) cURL library - your server must work with curl or url_fopen. (is correct) OpenSSL must be enabled. ( where is?) PHP file_get_contents() function must be available/unlocked. (where is?) In this last 2 points I just already ask to my Hosting privider to set it

update:

OpenSSL must be enabled. ( DONE is enabled now)

PHP file_get_contents() function must be available/unlocked. (where is?)

• Answer from my HP: filegetcontents() This function is similar to file(), except that filegetcontents() returns the file in a string, starting at the specified offset up to length bytes. On failure, filegetcontents() will return false. filegetcontents() is the preferred way to read the contents of a file into a string. It will use memory mapping techniques if supported by your OS to enhance performance.*

well? I still have the problem.. I need this probelm be fixed.. I pay my pro suscription since 2016/17 and I need it to work

I have exactly the same problem and would be very interested in a solution.

Any news?
