Hello Dude and Kriesi,

Thanks for replying so quickly.

I did the following steps:

In “wp-config.php” I added this line:
define(‘WP_MEMORY_LIMIT’, ’96M’);
(I was not sure WHERE to add it, so I put it above:
/* That’s all, stop editing! Happy blogging. */)

In default-constants.php I changed 40 to 96:
OLD:
// set memory limits
if ( !defined(‘WP_MEMORY_LIMIT’) ) {
if( is_multisite() ) {
define(‘WP_MEMORY_LIMIT’, ’64M’);
} else {
define(‘WP_MEMORY_LIMIT’, ’40M’);

NEW:
// set memory limits
if ( !defined(‘WP_MEMORY_LIMIT’) ) {
if( is_multisite() ) {
define(‘WP_MEMORY_LIMIT’, ’64M’);
} else {
define(‘WP_MEMORY_LIMIT’, ’96M’);

I have no idea why, but now Issues 1 and 3 are solved. For issue 2 I now cannot access the pages in the normal way but I assume that has to do with the activation of WPML. I will now start my lessons for WPML and I hope I will figure out what to do next.

Please let me know if my changes to the mentioned files could mess something up. If I don’t hear from you I just don’t touch things anymore and hope it will work all the way in the future. :-)

Thanks and best regards,
Claudia
