@bas Schuiling I had PHP 5.3 Due to your post I have changed to PHP 5.6 and now it works. Thank You
After update I get the following error message:
plugin cannot be activated due to fatal error.
Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM, expecting T_VARIABLE in /mnt/webp/e1/67/51408367/htdocs/WordPress_02/wp-content/plugins/maxbuttons/classes/installation.php on line 6
Is there any help?
Thanx
