After running WordPress and installing Jetpack, I encounter the following error when running the sitemap.xml of the website. The strangest thing was that the local server did work correctly.
I remembered that in local mode I had a similar error, which I fixed by removing the extra blank lines in the functions.php file after the “?>”, but this error was not the same:
«error on line 2 at column 1: Extra content at the end of the document” and looking at the source code it gave me: “<b>Fatal error</b>: Allowed memory size of 41943040 bytes exhausted (tried to allocate 20480 bytes ) in…»
Trawling the answer on san Google, I found the solution. The trick is to add to the “wp-config. php” the following line of code: «define( ‘WP_MEMORY_LIMIT’, ‘128M’ )».
That is, expand the memory to manage WordPress. We tested both the local server and the public server and it worked correctly and the sitemap did the same.
