The new release of Concrete5 5.6.1 is a nice upgrade. One of the irratating things that developers and users alike have run into, from time to time, is where you make a chance to a page on your website and either it doesn't appear or (even more irratating) it doesn't appear for everyone. The solution was to go and clear the site cache and usually that would fixed the problem.
From time to time we get calls from Concrete5 website owners whose sites were improperly built or their website has errors or need customization. We have over 3 years of experience with Concrete5 and have been working with the content management system almost since it went public. We specialize in fixing concrete5 websites.
