There are some of the useful WordPress tips that I have learnt.
How to create a empty/dummy top level menu?
Under Appearance->Menus, add a new custom menu item and put # in the URL field. Once the custom menu has been created, delete the “#” sign.
How to increase the upload size limit?
The maximum file size that can uploaded via WordPress Dashboard is to some extent “pre-programmed” by individual hosting provider. However, this can be altered to suit your needs.
1. FTP to your hosting account. Locate the “wp-admin” directory.
2. Create a file “php.ini” in plain text. Edit the file and input these two lines.
upload_max_filesize = XXM
post_max_size = XXM
Replace XX with the size desired.
3. Save the file.
