I am constructing a website with Wampserver 3.2.0 on my computer.
Using Joomla 3.9.16 and J51-Stella template.
Computer Windows 10, Firefox 75.0 (64 bits).

Problem:
1. BLOG menu on module position base-1b; RSS-info on module position base-1e.(Screenshot Base-Footer.jpg)

2. After activating BLOG the BLOG-messages are shown in the left quarter op the template width. From the second quarter part is shown the base and bottom info. The last even outsite the templatye width.(Screenshot blog1.jpg)

3. After activating READ MORE, the BLOG-messages are shown over the full template width. (Screenshot After-read-more.jpg)

The next actions are taken:
1. Reload of Joomla 3.9.16
2 Reload of J51-Stella
