Updated from version 6.4 to version 7.0 according to instructions from the site.

I noticed that there were errors
(1) When adding a new widget, for example, Web Monitoring, an unexpected server error appears. (attached screenshot No. 1)
(2) When editing the Graphics widget, a pop-up window appears for editing, but the chart itself is not visible and the navigation buttons - DatasetDisplay optionsTime periodAxesLegendProblemsReplacements are not clickable (attached screenshot No. 2)

Part of the access.log log when an error occurs
