With version 2024.2 there is a limit of 100 pages and 100 blog articles in the Evo version.
If you see that warning when you try to add a new page, your site probably already contains more pages than this limit.
If you want to add more pages, you need to reinstall the previous version of Evo (2024.1) and upload a backup of your unconverted project to 2024.2, or you can take advantage of a free upgrade with a Pro licence, with a similar expiry date to your current licence.
If you wish to proceed with this second option, please wait for STAFF

What do you mean with  please wait for STAFF 

Hi Aat, 

I confirm that, unfortunately, e-commerce, as well as some SEO-related functions are no longer available in the Evo edition of WebSite X5. In addition to this, a limit of 100 site pages and 100 blog articles that can be inserted per project has been set in the new version 2024.2. This choice was made based on some usage analysis of the Evo edition, with the aim of making the two editions of the program more clearly distinct.

Thus, to continue managing your project, there are two solutions:

>Do not upgrade to Evo 2024.2 and continue using 2024.1, which you can re-download from your profile and for which a backup copy of your project has been created.
>We can offer you a free upgrade to Pro. In this case, the Pro license will have the same expiration as your current Evo, and you will be free to decide, upon expiration, whether or not to extend it. The extension price of the Pro would be €99.97. If you do not extend, the program will remain active and normally usable, but you will not receive updates.

Let me know how you prefer to proceed, please.

Thank you! Best regards.

For the time being I will keep using 2024.1
