Can not save changes in the theme

Hi Flo,

Please check your php memory limit, install this plugin and post back with what it reports: https://www.ads-software.com/support/plugin/wp-memory-usage

Hi Benjamin,

thx for your reply!
the wp-memory-usage report says the following:

PHP Version : 5.3.10-1ubuntu3.21 / 64Bit OS
Memory limit : 128 MB
Memory usage : 98 MB

Every other funczion is wotking, only the customization of the theme does not!

It seems that you have a problem with PHP memory limit, please increase the memory limit to 256MB or more if necessary. Open your wp-config.php which is located in the root WordPress directory. Then add the following lines:

define('WP_MAX_MEMORY_LIMIT', '256M');
ini_set('memory_limit','256M');
