I'm trying to upload a 2MB xml file. In the "Import WordPress" dialog, where I specify the file, it says that the maximum file size is 1MB. The default upload_max_size from my web hoster is 40MB. I tried to manually set the upload_max_size in a php.ini and in the wp-config.php, but it stays at 1MB.
My memory limit is 90MB and should also be sufficient.
The upload doesn't work
Fatal error: Out of memory (allocated 50593792) (tried to allocate 8193 bytes) in /homepages/30/..../wp-content/plugins/wordpress-importer/parsers.php on line 655
Any idea what's causing the problem?
