Thank you.

Please contact your provider to force update using the following instruction.
1. SSH to the server as root and run this command.

rm -f /var/cpanel/rvglobalsoft/rvsitebuilder/var/INSTALL_COMPLETE.php
rm -f /var/cpanel/rvglobalsoft/rvsitebuilder/rvsitebuilderversion.txt
perl /usr/local/cpanel/whostmgr/docroot/cgi/rvsitebuilderinstaller/autoinstaller.cgi

2. Go to root WHM/RVSiteBuilder, it will automatically rebuild the database for you.

To force update both steps need to be done. It still keeps your previous data, configuration and translation (given that you do not edit files directly but edit from RVSiteBuilder Manager). If doesn’t work, please submit me the login information to the account in question or attach me the snapshot of what you did and its result.

Thank you.

Solution

1. Try adding this line to your wp-config.php file:
define('WP_MEMORY_LIMIT', '64M');

2. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 32M try 64M:
memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)

3. If you don't have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 64M

4. Talk to your host.

Thank you.

You can check the version using the below command

#uname -mrs   to check how many bit 64 or 32

#cat /etc/redhat-release  this to check the version
