To be kicked

It was a very small thing, which made me exhausted. In addition, I didn't have such a troubled mentality, so I almost deleted the blog program. Fortunately, I was a little reluctant and finally kept it.

Here's the thing:

1. One day, the hedgerow host upgraded the host. After the upgrade, the PHP version configuration was reduced to 5.6 because of the PHP version problem. This was also because of the upgrade. In the database, a field in the article table would not report an error in the previous version of MYSQL. In the upgraded version, an error is reported. Articles cannot be submitted (the second thunder is buried here)

2. After many times of trouble, the article cannot be submitted, and I am prompted that I have no value. After listening to debugging, I still did not expect that it was the article table and the custom field table. The problem cannot be solved. I also suspected that the upgrade was incompatible.

3. I also upgraded the blog program to 1.2. At this time, there was no way to save it. The front end could not be opened and the back end could not be opened. It should not be like this. I can open it locally. Later, it was found through phpinfo that the version on the host is 5.6. Then I adjusted the local version to 5.6, and found that it could not be opened. Finally, I found the problem.

4. Turn the PHP of the host to 7.2, and the background can be opened normally.

5. An error is reported as an article is submitted. A field in the article table can be checked as blank and saved. The article can be submitted successfully. So far, the problem is solved.

6. Fix some small problems of the blog.

7. The unreasonable parts of the theme have also been changed, and the redundant plug-ins have also been deleted. A new article traffic statistics plug-in has been replaced, and the previous compatible plug-ins have been modified.
