re: 'Please check this URL & let me know if you found the problem.'
I am not sure what you mean you 'if I found the problem'.
I have checked the URL that you provided.. it works.
I have also changed cache_handler = 'memcached' to cache_handler='file' on our test system but am seeing the same errors:
Symfony\Component\ErrorHandler\Error\
ClassNotFoundError
and
Error
Failed opening required '/var/www/html/public/administrator/components/com_sppagebuilder/builder/classes/base.php' (include_path='.:/usr/local/lib/php')
I am not sure if one is causing the other.
I have also rechecked for the file that it's complaining about and : /var/www/html/public/administrator/components/com_sppagebuilder/builder is not there.
Is it possible that the pagebuilder update removed the folder?
I have reinstalled PageBuilder and that folder is still not there. The missing class now seems to be in : /var/www/html/public/components/com_sppagebuilder/builder/classes/
Strangely Joomla is reporting that the issue is on line 23 of this function: /var/www/html/public/components/com_sppagebuilder/parser/addon-parser.php:23
The last line of this code is failing:
require_once DIR . '/addons.php';
require_once DIR . '/../helpers/helper.php';
require_once DIR . '/../helpers/addon-helper.php';
but as far as I can see from the /var/www/html/public/components/com_sppagebuilder/parser/ folder, ../helpers/addon-helper.php is there.
strangely the NEXT line attempts to load 'base.php':
require_once JPATH_ROOT . '/components/com_sppagebuilder/builder/classes/base.php';
but it places base.php in the correct place.... Assuming tha thte error is right but the location is wrong.. why would joomla be attempting to load from: /var/www/html/public/administrator/components/com_sppagebuilder rather than: /var/www/html/public/components/com_sppagebuilder??
I get where you are going re the cache being a possible issue.
There is a folder here: administrator/cache/sppagebuilder/
There are some largeish file in there.. is that folder safe to delete?
I've tried deleting /cache but that's not helped.
re your ftp question.. as noted before .. profiding ftp is a problem because of how/where we run these containers. Did 'FF Explorer' not give you access to the files that you needed to see?
Thanks
