Troubleshooting: Number of settings being saved exceeds PHP max input vars
As of Beaver Builder 2.2.3, you might see a popup message that the PHP Max Input Vars setting is lower than the number of settings being saved.
The PHP max_input_vars setting limits how many input variables can be accepted. This is a security feature for DDoS attacks, but in some cases the limit might need to be increased to accommodate the number of post variables that Beaver Builder is saving.
Contact your hosting provider and ask them to increase the
max_input_vars limit. Use the error message as a guide to how high you need the limit to be.
