This is a software issue, #PPPM-1541, which will be fixed in future Web Presence Builder updates.
There are three different ways to resolve the issue:
- You can increase PHP limits according to this Knowledgebase article: #117909 Web Presence Builder: "Unable to connect to Web Presence Builder"
- For versions of Web Presence Builder higher than 11.5, remove surplus pages from the site to make it smaller.
As of version 11.5, the number of pages per site is limited to 500. To increase site performance, you may decrease the page limit in the configuration file (
maxPagesNumber = 400
By default, the limit is set to 500.
IMPORTANT: Do not change the limit to more than 500.
